멀티스태틱 PCL 개발을 위한 산란신호 모의 = Scattering Signal Model to Develop Multi-Static Passive Coherent Location Apparatus

다국어 초록 (Multilingual Abstract)

In this paper, we proposed a scattering signal model to develop a multi-static passive coherent location(PCL) apparatus using frequency modulation(FM) radio broadcasting. The proposed method first generates in-phase and quadrature(IQ) signals and FM broadcast signals, according to the protocol, and simulates the clutter signal considering the terrain between the transmitter and the receiver. The reflection signal from the target is simulated by considering the time-varying Doppler frequency and radar cross section.
The sampling timing of the IQ data is delayed in the time domain to minimize the Doppler effect’s computation time. The measured antenna manifold is applied to simulate the received IQ signal through the array antenna. Finally, the generated IQ signal is verified by extracting the Doppler frequency and information regarding the target’s distance in the ambiguity range Doppler map.
