Executive Summary The present document covers the essential requirements for efficient use of radio spectrum by Coastal Surveillance, Vessel Traffic Services and Harbour Radars (CS/VTS/HR) in the bands between 8 500 MHz to 10 000 MHz using pulsed signals and a transmitting power up to 100 kW. The present document includes necessary changes due to adaption to the new Radio Equipment Directive [i.1]. SIST EN 303 135 V2.1.1:2016

ETSI ETSI EN 303 135 V2.1.1 (2016-06) 6 Introduction The present document intends to present a harmonized way of proving compliance to the essential requirements of the RE Directive [i.1] for important types of radar like Coastal Surveillance (CS), Vessel Traffic Services (VTS) and possibly harbour radars. The emission limits implemented arise from ECC/Recommendation (02)05

[i.3] and ERC/Recommendation 74-01 [i.4]. The test methods used arise from Recommendation ITU-R M.1177-4 [2] and Recommendation ITU-R SM.1541-5 [1]. NOTE: The present document is closely related to ETSI EN 303 213-6-1 [i.11] which covers essential requirements for radars used in airport SMGCS systems, but which use largely the same type of radar technology. The present document is part of a set of standards developed by ETSI and is designed to fit in a modular structure to cover all radio and telecommunications terminal equipment within the scope of the RE Directive [i.1]. The modular structure is shown in ETSI EG 201 399 [i.7].

ETSI ETSI EN 303 135 V2.1.1 (2016-06) 7 1 Scope The present document applies to X-band radar sensors intended for use in Vessel Traffic Services (VTS), Coastal Surveillance (CS) or Harbour Radar Systems with the following characteristics: • Utilizing modulated or unmodulated pulses. • Transmitter Peak Envelope Power up to 100 kW. • The transceiver-antenna connection is using a hollow metallic rectangular waveguide. • The antenna is rotating, waveguide- based and passive. • At the transceiver output an RF-circulator is used. NOTE 1: Since transceiver and antenna are hollow metallic rectangular waveguide based, the frequency range for measurements that needs to be addressed covers 6,56 GHz to 26 GHz. The lower limit of this frequency range is obtained as cut-off frequency of the combination of WR112/R84 taper section and a WR90/R100 Waveguide as defined by IEC 60153-2 [i.2]. The upper limit corresponds to the upper limit stated in ERC/Recommendation 74-01 [i.4]. Other types of waveguide may be used by the same principles to obtain complete measurement coverage of the frequency range of the output flange of the equipment under test. NOTE 2: Since at the transceiver output an RF circulator is used, it is assumed that the transceiver characteristics remain independent from the antenna. NOTE 3: According to article 5 of the ITU Radio Regulations [i.5] there are a number of bands between 8,5 GHz and 10 GHz that are allocated to Radiolocation service. There are national deviations to the detailed band usages, but the basic spectrum usage regulation is the same. Table 1: Radiolocation service frequency bands [GHz] 8 500 - 8 550 8 550 - 8 650 8 650 - 8 750 8 750 - 8 850 8 850 - 9 000 9 000 - 9 200 9 200 - 9 300 9 300 - 9 500 9 500 - 9 800 9 800 - 9 900 9 900 - 10 000

The present document contains requirements to demonstrate that "...radio equipment shall be so constructed that it both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference" [i.1]. In addition to the present document, other ENs that specify technical requirements in respect of essential requirements under other parts of article 3 of the Radio Equipment Directive [i.1] may apply to equipment within the scope of the present document. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

The equipment shall comply with all the technical requirements of the present document at all times when operating within the boundary limits of the declared operational environmental profile. 4.2 Conformance requirements 4.2.1 Transmitter requirements 4.2.1.1 Operating frequency 4.2.1.1.1 Definition The transmitter of a pulsed radar produces microwave pulses, which cause a broad frequency spectrum, depending on the pulse duration. In the present document the operating frequency is considered to be the frequency of the microwave emission during the transmitting pulse and is represented by the spectral line of highest amplitude. NOTE: It is only practicable to indicate an operating frequency for radars with unmodulated pulses. In this case a limit for the frequency tolerance is specified. For radars with modulated pulses such a limit is not applicable. In any case the occupied bandwidth is completely contained in the allocated frequency band(s). 4.2.1.1.2 Limits The frequency tolerance for a radar applying unmodulated pulses shall be ±30 MHz. For all radar types covered by the present document the occupied bandwidth of the signal shall be contained completely within the allocated band in use (e.g. 9 300 MHz to 9 500 MHz) in all operating modes. 4.2.1.1.3 Conformance The conformance tests are specified in clause 5.3.1.1. 4.2.1.2 Transmitter power 4.2.1.2.1 Definition In the present document the transmitter power of a pulse radar is considered to be the peak value of the transmitter pulse power during the transmission pulse (PEP). If the transmitter power varies over the azimuth, the highest PEP over at least one rotation period has to be used. The transmitter power shall be referenced with respect to the output port of the radar transmitter. SIST EN 303 135 V2.1.1:2016

ETSI ETSI EN 303 135 V2.1.1 (2016-06) 11 If the transmitter power can be varied according to azimuth, the highest PEP value measured during a period equal to at least one rotation period shall be used. 4.2.1.2.2 Limits The transmitter power shall be as specified by the manufacturer with an accuracy of at least ±2 dB. The peak power value shall not exceed 100 kW (50 dBW). 4.2.1.2.3 Conformance The conformance tests are specified in clause 5.4.1.2. 4.2.1.3 Out-of-band emissions 4.2.1.3.1 Definition An important parameter of the Out-of-Band (OoB) emissions mask of the radar is the -40 dB bandwidth. Annex 8 of Recommendation ITU-R SM.1541-5 [1] specifies the -40 dB bandwidth specified for various types of waveforms (e.g. pulsed radar signals). With the following assumptions which apply to most airport surface movement radars these specifications can be further simplified: • the radar is operating in a band within the limits 8 500 MHz to 10 000 MHz; • the pulse power is below 100 kW; • the pulse rise time tr is greater than 0,0094 t, where t is the pulse duration. With the aforementioned assumptions the -40 dB bandwidth (B-40) for primary non-FM pulse radars can be determined as follows: rttB×=−6.740 Where: • t is the pulse duration; • tr is the rise time in the case of a trapezoidal pulse. NOTE: For typical values of a pulse duration of t = 50 ns and a rise time of tr = 10 ns the formula above yields a -40 dB bandwidth value of 340 MHz.

For radars with multiple pulse waveforms, the B-40 bandwidth should be calculated for each individual pulse type and the maximum B-40 bandwidth obtained shall be used to establish the shape of the emission mask. For radars with a highly asymmetrical spectrum, the B-40 dB bandwidth can be offset from the frequency of maximum emission level, but the necessary bandwidth, BN and preferably the overall occupied bandwidth should be contained completely within the allocated band as stipulated in section 4 of Annex 8 of Recommendation ITU-R SM.1541-5 [1]. The application of this rule is illustrated in Figure 1. SIST EN 303 135 V2.1.1:2016

Figure 1: Application of the offset-rule for the Out-of-Band emission limit mask For FM pulsed radars the B-40 can be calculated as follows: ()[]()()[]{}3&&&53.040111,,,,ln5.1fffallriseffallrriseSfallrisefallrisefallrisefallriseCCttBtBtBwhereBBBBMaxBBBMinBBB⋅⋅=⋅=⋅=++⋅⋅⋅+⋅=−ττττπ Where: B-40 is the -40 dB bandwidth in Hz; BC is the bandwidth of the frequency deviation (total frequency shift during the pulse generation); BS is the maximum range over which the carrier frequency will be shifted, BS equals zero for non-frequency hopping cases. It is zero in case of a single carrier frequency; τ is the pulse length including rise & fall times; tr is the risetime in seconds; tf

is the falltime in seconds. For systems with multiple carriers, the OoB domain should start at the edges of the total assigned bandwidth. This means that the effective B-40 is from the lower end of the calculated B-40 of the lowest radar frequency to the high en
