Research on Integrated Waveform of MSK-LFM Radar Communication for Anti Multipath Interference

Given the miniaturization of the combat platform and the increasing complexity of the combat environment, this paper proposes a radar communication integration scheme. The scheme adopts minimum frequency shift keying and linear frequency modulation (MSK-LFM) integrated signal. Aiming at the problem that the bit error rate of the integrated signal will deteriorate in the presence of multipath interference, this paper uses direct sequence spread spectrum technology to optimize the integrated signal, which can effectively reduce the bit error rate. The simulation results show that this method can reduce the influence of multipath interference, improve frequency utilization and system detection accuracy, and reduce the bit error rate of the system.
