摘要
针对雷达目标检测和射频隐身波形综合设计问题，本文提出了一种在隐身测度的约束下求解最优检测波形的设计方法。该方法在基于最大化信干噪比准则下，使用最大边缘分配算法将有限的能量离散化并在频域上将离散的能量进行分配得到满足隐身测度约束条件的最优探测发射波形能量谱，并使用波形能量谱进行时域波形的合成。仿真实验表明，该方法得到的波形与传统常用的隐身波形相比有更好的隐身性能和探测性能。

Abstract
For the waveform design problem of joint radar target detection and RF stealth, this paper proposes a design method to solve the optimal detection waveform under the constraint of stealth measure. This method uses the maximum marginal allocation algorithm to discretize the finite energy and allocate the discrete energy in the frequency domain to obtain the optimal detection emission waveform energy spectrum that satisfies the stealth measurement constraint based on Maximum Signal to Interference and Noise Ratio criterion. Then the waveform energy spectrum is used to synthesize the time domain waveform. Simulation experiments show that the waveform obtained by this method has better stealth performance and detection performance compared with the commonly stealth waveform.
