摘要

提出了利用压缩感知解微多普勒模糊的方法。由于目前雷达无法实现发射脉冲的随机性，采用电磁仿真软件FEKO来实现具有随机发射时刻的雷达回波模拟，用于算法验证。仿真过程中，考虑微动目标运动的复杂性，采用FEKO结合MATLAB的方式实现目标姿态的动态更新。首先由MATLAB计算出每个稀疏时刻目标的运动状态，然后把参数传递给FEKO，获得不同时刻对应的姿态角下目标的电磁散射数据，最后利用本文算法解出无模糊的微多普勒频率。对5种不同的微动模型进行仿真，仿真结果均与理论结果一致，由此验证了该算法的可行性和仿真模型的有效性。

Abstract

The method of understanding and resolving the micro-Doppler was proposed. As the radar cannot achieve the randomness of the transmission pulse

and the electromagnetic simulation software FEKO was adopted to achieve the radar echo simulation with random emission time

and it was used for algorithm verification. In the progress of simulation

by considering about the complexity of the jogging target movement

the combination of FEKO and the MATLAB was adopted to realize the dynamic updating of the target's posture. Firstly

the motion state of each sparse moment target was to be calculated by MATLAB

then the parameters would be transmitted to the FEKO so as to obtain the electromagnetic scattering date under the corresponding attitude angle of different moments

at last

the micro-Doppler frequency without blurry would be worked out with the algorithms hereof. The simulation was executed to five different jogging models

and the simulation results have no difference with the theoretical results

therefore

the feasibility of the algorithm and the efficiency of the simulation model can be verified.
