Experimental License Modification Request 1 Purpose of Operation Raytheon Integrated Defense Systems (IDS) to development of the prototype radar requires the testing of more waveforms, i.e. pulsed Frequency Modulated (FM Chirp) waveforms over the same frequency range 5.4 – 5.5 GHz. File Number: 0631-EX-CM-2018 - Station Locations: FIXED/MOBILE - Effective: 10/21/2018 - Expiration: 10/21/2019 Experiment 1: Summary - Radar operating in C-band, on the ground, low power, chirp waveforms. Call Sign: WG2XVY,: Continued development of the prototype radar requires the testing of more waveforms, i.e. pulsed Frequency Modulated (FM Chirp) waveforms over the same frequency range 5.4 – 5.5 GHz. In addition, experiments are planned that are intended to demonstrate the operability of the radar with varying types of targets. The targets will be presented to a radar via a Synthetic Target Generator. It is essential that radar performance be demonstrated in a real-time radar environment, which allows for the analysis of over-the-air effects that are not easily modeled in simulation. Synthetic Target Generator (STG) will be used to present the radar with targets with varying characteristics. The STG will receive signals transmitted by the radar and will process them to add simulated targets to the return signal. Waveforms: Waveforms will be utilized by the prototype radar / STG: Frequency Modulated-Pulsed programmable with up to a 75 MHz chirp slope and programmable pulse width from 1.0μsec to 20.0msec, 30.0kHz max rep rate. Emissions Modulation is 75MF1N (75 MHz Bandwidth, Unmodulated Carrier with varying frequency modulation, single channel (no sub-carrier), No additional information transmitted). Effective Radiated Power of less than 500 watts peak. Transmitter Power less than 5 watts peak. Custom Transmitter.

Experiment 2: Summary – Communications Link Testing, operating in 30 MHz to 2,000 MHz range, Full duplex on the ground, low power, AM, SSB, NBFM, and PSK waveforms. New experiment to test a ground to ground link using narrow band modulation. Frequency of experiment #2 divided into 3 operating bands: Band A) 54.0 -> 60.0 MHz Band B) 420.0 -> 426.0 MHz Band C) 1,850.0 -> 2,000.0 MHz Emissions Modulation is 25KD2W (25 kHz, Both Amplitude and Phase modulated, Single channel with modulating subcarrier, with both voice (telephony) and data). Effective Radiated Power of less than 20 watts peak. Transmitter Power less than 10 watts peak. Custom Transmitter. Experiment 3: Summary – Communications Link Testing, operating in 30 MHz to 2,000 MHz range, Full duplex, ground to Air to ground, low power, AM, NBFM, and PSK waveforms. New experiment to test a ground to air and air to ground link using narrow band modulation. Frequency of experiment #3 divided into 3 operating bands: Band A) 54.0 -> 60.0 MHz Band B) 420.0 -> 426.0 MHz Band C) 1,850.0 -> 2,000.0 MHz Emissions Modulation is 25KD2W (25 kHz, Both Amplitude and Phase modulated, Single channel with modulating subcarrier, with both voice (telephony) and data). Ground Effective Radiated Power of less than 20 watts peak. Transmitter Power less than 10 watts peak. Air Effective Radiated Power of less than 5 watts peak. Transmitter Power less than 2 watts peak. Custom Transmitter.
