This study has been made to improve the detection capacity of radar using phase coded waveforms especially the Golay set sequence while keeping the sidelobe ambiguity function to the possible minimum. This Letter begins with a description of Golay complementary sets construction from a graph and a determination of the parameters on which they depend to be optimised after. Then, the simulated annealing (SA) algorithm has been proposed to deal with low ambiguity problem of the Golay set, due to its simplicity and also to its effectiveness to solve this kind of problem. Simulation results show that the optimisation with SA has impressively improved the sidelobe rejection of Golay set sequences with a gain of up to 20 dB.

在雷达应用中使用 SA 改进 Golay 集序列的旁瓣

本研究旨在提高使用相位编码波形特别是Golay 集序列的雷达的检测能力，同时将旁瓣模糊度函数保持在可能的最小值。这封信首先从图中描述了 Golay 互补集的构造，并确定了它们之后要优化的参数。然后，由于其简单性和解决此类问题的有效性，人们提出了模拟退火（SA）算法来处理Golay集的低模糊度问题。仿真结果表明，SA 的优化显着改善了 Golay 集序列的旁瓣抑制，增益高达 20 dB。
