Abstract
AbstractIn the configuration scenario of bistatic radar, clutter tends to be complicated, which will be aggravated by the moving state of non-cooperative radiators. Therefore, a clutter modeling method of non-cooperative airborne radiators is proposed. Based on the background of non-cooperative radar emitter and ground receiving station, the clutter spectrum under the system is constructed and its distribution is studied theoretically. Simulation results show that the influence of clutter on radar decreases with the increase of distance, when the radiation source location and velocity are different, the greater the clutter freedom is, the greater the complexity of clutter spectrum is. The clutter modeling method of non-cooperative moving emitter extends the clutter model and lays a foundation for clutter suppression and target detection of non-cooperative emitter radar configuration.
