  1. 1. VHF Pulse Compression Radar Goals of the project: Development of an experimental radar transceiver with asociated signal and data processing for detecting unexpected occured, low-height operated, small reflectable, flying targets, -using the existing antenna mechanics of type P-18 VHF radar. Technical objectives: Design and implementation of a state of the art equipment with sub-pulse modulated transmitter, matched filter pulse compression receiver, full semiconductor based, computer controlled, remote operable, ready for system integration. 60 Impulse Compression 0.5 Channel 64us pulse with 1us symbol rate subpulse modulation is transmitted, in the receiver it is compressed back to 1us to provide the required resolution. 80 1 Pulse compression: 0 -0.5 -1 0 0.5 1 Time 40 20 0 -20 0 1.5 0.5 1 Time x 10 -3 1.5 Installed type P-18 “Spoon Rest” VHF radar x 1 0- 3 Implementation: using advanced software radio technology Analog RF signal processing High-speed domain conversion Operating environment of the device: Digital signal processing algorithms Construction: 12U height 19” rack PA’s power supply PA LNA Booster T/R switch P-18 antenna shelter P-18 shelter Rotation control Rotation signal N U D Rotation interface Direction RS-232 Antenna connection Transceiver subsystem RHP/ASOC Signal and data proc. RS-232 IP Display subsystem Signal- and data processing software: Isolation transformer Platform computer PP indicator software: Low-level signal connections IF and trigger connections Special thanks to: Az eddig megvalósított legteljesebb radar fejlesztési projekt www.sagax . www.sagax.hu Sagax, Ltd.
