Abstract

Radar target high range resolution profile splicing is a premise for the application of one-dimension high range resolution profile in radar target recognition. The influence of target motion on high range resolution profile of modulated frequency stepped radar is analyzed, while cyclic shift discard profile splicing algorithm which avoids extracting loss is proposed. The algorithm overcomes the effects of target motion on traditional range profile splicing algorithm. Simulation results validate the correctness of theoretical analysis.

Abstract

A nonparametric computationally efficient algorithm is proposed for micro-Doppler frequency estimation, assuming that this non-linear micro-Doppler frequency is approximate linear frequency in short-time intervals. In this algorithm, we use Radon-Wigner transform in short-time intervals to estimate micro-Doppler frequency. Simulation results confirm the effectiveness of the proposed method.
