Project poster: Software Defined Radar

  1. 1. www.www.sagaxsagax..huhu SagaxSagax,, LtdLtd.. HallerHaller u. 11-13.u. 11-13. 1096 Budapest, HUNGARY1096 Budapest, HUNGARY VHF Pulse Compression RadarVHF 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. Installed type P-18 “Spoon Rest” VHF radar Implementation: using advanced software radio technology Analog RF signal processing High-speed domain conversion Digital signal processing algorithms T/R switchLNA Low-level signal connections IF and trigger connections PAPA’s power supply Isolation transformer Platform computer Booster P-18 antenna shelter P-18 shelter Transceiver subsystem Signal and data proc. Display subsystem Rotation control Rotation signal Antenna connection RS-232 RHP/ASOCRotation interface N U D Direction RS-232 IP Operating environment of the device: Signal- and data processing software: PP indicator software: Construction: 12U height 19” rack Az eddig megvalósítottAz eddig megvalósított legteljesebblegteljesebb radarradar fejlesztési projektfejlesztési projekt Special thanks to: Pulse compression: 64us pulse with 1us symbol rate subpulse modulation is transmitted, in the receiver it is compressed back to 1us to provide the required resolution. 0 0 . 5 1 1.5 x 1 0- 3 - 2 0 0 2 0 4 0 6 0 8 0 Time ImpulseCompression 0 0.5 1 1 . 5 x 10 -3 - 1 -0.5 0 0.5 1 Time Channel
