Abstract

The anti-jamming performance of array systems can be improved markedly by the technique of adaptive digital beamforming (ADBF), which is applied widely in modern radar and communication systems. In linear frequency modulation continuous wave (LFMCW) systems, the target information is usually extracted by range-Doppler processing. In this paper, the application problem of ADBF in the LFMCW system is discussed, and the system schemes of ADBF combining range-Doppler processing are proposed. It is proved that the schemes are feasible and effective, and the signal detection performance can be improved markedly.
