摘要:
针对雷达与通信频谱交叠频段设计阻带波形涉及较高计算复杂度的问题,提出了基于改进迭代算法的阻带波形设计的方法。该方法旨在不考虑雷达检测性能的情况下设计低计算复杂度雷达频谱阻带恒模波形。主要思路是将重叠频段信号能量和信号自相关旁瓣约束加权求和作为目标函数,自相关旁瓣约束采用信号相似性约束而非精确的旁瓣水平约束,最终利用梯度下降思想以及迭代方法寻找最优波形。该方法不涉及求解半定规划(SDP)问题且避免了分步优化过程,降低了计算复杂度。仿真结果表明,该方法能得到在指定频段带有阻带的优化波形,而且能够更加快速地得到指定频段有效降低的恒定幅度优化信号,同时具有良好的自相关特性。
Abstract:
In order to solve the problem of high computational complexity for the design of stopband waveform in the overlapping frequency band of the radar and the communication spectrum, a method for designing the stop band waveform based on the improved iterative algorithm was proposed. A low-computational complexity radar spectrum stop-band unimodular waveform was designed without taking into account the radar detection performance. The method was to take the weighted sum of signal energy and signal autocorrelation sidelobe constraint as objective function, and the autocorrelation sidelobe constraint adopted signal similarity constraint rather than exact sidelobe horizontal constraint, and finally uses the idea of gradient drop and iterative method to find the optimal waveform. The method did not involve solving the semidefinite programming (SDP) problem and avoided the step-by-step optimization process and reduced the computational complexity. Simulation results showed that the method could obtain the optimization waveform with stopband in the specified frequency band, got the constant amplitude optimization signal with effective reduction in the specified frequency band more quickly, and had good autocorrelation characteristics at the same time.
