A 24 GHz band FM-CW radar system for detecting closed multiple targets with small displacement

In this paper, detection method for 24 GHz band FM-CW radar system under closed multiple targets with small displacements environment is proposed, and its performances are analyzed. The proposed detection method was used a tunable FIR filter for signal processing, and the distance and small displacement can be separated for each target correctly from the received signal including all of signals from the targets at the FM-CW radar. Computer simulations were carried out for evaluating the proposed detection method for FM-CW radar and analyzing the performance according to the parameters under closed multiple targets environment. The results show that the proposed detection method can detect both the distance and small displacement correctly under closed multiple targets environment.
