机载高重复频率雷达多普勒中心估计方法

Abstract

Abstract:

Due to strong coherence between adjacent pulses for a high pulse repetition frequency, a method for estimating the Doppler centroid using multiple pulses is presented. The method constructs the eigenvector corresponding to the largest eigenvalue of the phase covariance matrix, and then the Doppler centroid is estimated based on the eigenvector. The estimation accuarcy of the method is improved about 5 dB compared to that of the correlation function method. Simulation results are given to demonstrate the effectiveness of the method.

Key words: airborne, radar, Doppler, high pulse repetetion frequency, eigenvector
