摘要

导弹飞行速度快,对目标信息获取实时性要求高,而弹载雷达开机后往往不具备充足的目标信息,无法快速准确地对目标进行检测。针对以上问题,文中提出了一种基于线性最小均方误差(LMSE)的弹载雷达波形设计方法,该方法基于认知理论综合考虑杂波及色噪声对波形优化的影响,利用注水法实现波形优化。仿真实验表明,该方法优化的波形能有效克服杂波与色噪声影响,降低目标频率响应估计误差,同时显著提高弹载雷达对目标的检测性能。

Abstract

The missile has fast flight speed and high requirement for real-time acquisition of target information, however, the missile borne radar often does not have enough target information when it is switched on, so it can not detect the target quickly and accurately. Aiming at the above problems, a waveform design method of missile-borne radar based on linear minimum mean square error (LMSE) was proposed in this paper. In this method, the influence of clutter and color noise on waveform optimization was considered based on the cognitive theory. More important, the waveform optimized by water-filling method. The simulation results show that the optimized transmitting waveform can effectively overcome the influence of clutter and colored noise, reduce the estimation error of target frequency response, and the detection performance of missile borne radar target is improved significantly.

Key words： missile-borne radar; waveform design; mean square error; target detection
