摘要
研究了MIMO雷达目标位置回波的模糊函数。比较了相关目标模糊函数和非相关目标模糊函数的性能,介绍了MIMO雷达回波信号模型的基本原理。仿真证明,对于MIMO雷达相关处理性能优于非相关处理性能,能提高目标位置估计的分辨力。采用相关处理模糊函数的定位仍受噪声影响,对均方定位误差性能进行了分析。
The ambiguity function of the reflected waveform of the scatters detected by MIMO Radar is studied. A comparison in performance is made between the coherent and non-coherent ambiguity function, and an introduction to the reflected signal model of MIMO radar is given. The simulation results show that as for MIMO radar, the coherent ambiguity function has advantage over the non-coherent one of higher resolution of the scatter＇s location, although the white Gaussian noise exists as disturbance. The performance of ambiguity function is also analyzed.
