| Popis: | A method for simulating and processing a coherent low probability of intercept (LPI) radar transmitting a continuous wave (CW) polyphase code (i.e. P4-RSNS) in coherent sea clutter and noise is discussed. A design process to achieve the necessary LPI radar range, Doppler, and coherent integration processing gains and associated losses is demonstrated for a 10 dBsm target at a maximum range of 9 km, and shown to have a false alarm rate of 10-6 and a detection rate of 0.9. The total processing time is around one second. Office of Naval Research |
