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.

用于测距的约束雷达波形设计

范围分析是指沿雷达倾斜范围的目标响应的测量。它在自动目标识别中起着重要作用。在本文中，我们考虑了发射波形的设计，以提高雷达系统的测距性能。针对波形优化问题，采用了两种设计指标：一种是使接收信号与目标冲激响应（TIR）之间的互信息最大化。另一种方法是最小化估计TIR的最小均方误差。另外，考虑了对波形的实际约束，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。
