Performance Simulation Analysis of Non-Cooperative Multistatic Radar System
Aiming at the problem that stealth ships with low RCS(radar cross section)are difficult to be detected by ordinary monostatic radars,a non-cooperative multistatic radar system is proposed to detect sea targets.A maritime scene is created,in which multiple merchant ships emit electromagnetic waves in the S-band(3 GHz)as opportunistic radars.A frigate-sized warship acts as a radar system receiver,and the targets are assumed to be a cargo ship and a stealth warship.The professional electromagnetic software is used to simulate sea targets,and the bistatic RCS data of or-dinary cargo ships and stealth warships are calculated.The MATLAB simulation model is established to study the detec-tion coverage of non-cooperative multistatic radar.The bistatic RCS simulation using FEKO shows that an optimal multi-static radar system geometry and system configuration are found by varying the number of transmitters and the distance from the transmitter to the receiver.
