约束雷达距离像波形设计

Constrained Radar Waveform Design for Range Profiling

Bo Tang, Jun Liu, Hai Wang, Yihua Hu

摘要:

距离剖面测量是指沿雷达倾斜距离测量目标响应。它在自动目标识别中起着重要的作用。本文从发射波形设计的角度出发,研究了提高雷达距离像性能的方法。波形优化问题采用两个设计指标:一是最大化接收信号和目标脉冲响应(TIR)之间的互信息;二是最小化TIR估计的最小均方误差。此外,考虑了波形的实际约束,包括能量约束、峰均功率比约束和频谱约束。基于最小化-最大化,我们提出了一个统一的优化框架来解决约束波形设计问题。数值算例表明了该算法合成波形的优越性。

英文摘要:

Range profiling refers to the measurement of target response along the radar slant range. It plays an important role in automatic target recognition. In this paper, we consider the design of transmit waveform to improve the range profiling performance of radar systems. Two design metrics are adopted for the waveform optimization problem: one is to maximize the mutual information between the received signal and the target impulse response (TIR); the other is to minimize the minimum mean-square error for estimating the TIR. In addition, practical constraints on the waveforms are considered, including an energy constraint, a peak-to-average-power-ratio constraint, and a spectral constraint. Based on minorization-maximization, we propose a unified optimization framework to tackle the constrained waveform design problem. Numerical examples show the superiority of the waveforms synthesized by the proposed algorithms.
