摘要
通过对跳频信号功率谱密度分析,指出经典周期图方法的不足,经过分析改进,得出跳频信号功率谱密度估计合适的方法和参数。仿真结果表明,改进方法具有良好的可行性功率谱估计性能。
The FH signal power spectrum density is analyzed and the shortcomings of the classical periodogram methods are pointed out.An appropriate method for and the parameters of FH signal power spectrum density estimation is given.Simulation results show that the improved method is feasible and has good estimation function.
