This work addresses the radar waveform design problem using phase-coded waveforms especially Golay complementary pair (GCP). Thus, a new shaping of GCP is proposed and the good performance of this shaping in terms of ambiguity function sidelobe (SL) rejection is shown. With the new shaping, a gain of at least 10 dB is easily obtained in comparison with the standard GCP. In order to improve the performance of the proposed waveform, two optimization algorithms are proposed to deal with low sidelobe ambiguity function problem, a very hard combinatorial optimization problem. The first one is the simulated annealing algorithm, a local search algorithm. The second represents the genetic algorithm-based global search strategy. Simulation results are provided and demonstrate that both types of algorithms decrease the SL rejection of the ambiguity function for all tested instances.

一种新的Golay序列整形的低旁瓣雷达模糊度函数的优化

这项工作解决了使用相位编码波形特别是 Golay 互补对 (GCP) 的雷达波形设计问题。因此，提出了一种新的 GCP 整形，并显示了这种整形在模糊函数旁瓣 (SL) 抑制方面的良好性能。使用新的整形，与标准 GCP 相比，可以轻松获得至少 10 dB 的增益。为了提高所提出波形的性能，提出了两种优化算法来处理低旁瓣模糊函数问题，这是一个非常困难的组合优化问题。第一个是模拟退火算法，一种局部搜索算法。第二个代表基于遗传算法的全局搜索策略。
