A Low-Complexity Parameter Estimation Algorithm for an Integrated Radar-Communication Waveform With Cross-Mode Interference

For the communication receiver of a joint radar-communication system based on linear frequency modulation (LFM), the estimation accuracy of the carrier frequency, chirp rate, and other parameters will seriously affect communication performance. Unfortunately, in addition to the parameter offsets caused by the harsh environment, cross-mode malicious interference, whose instantaneous frequency (IF) ...
