Abstract :
This paper focuses on the problem of Doppler spread caused by high-speed target motion during coherent accumulation period for linear FM signals, then a Dual linear FM composite algorithm is proposed. The theory analysis and simulation are presented, and the conventional processing algorithm is compared with the proposed algorithm based on the echoed signal. The results shows that the composite algorithm is useful and able to be realized in engineering.
