摘要
该文提出了一种估计空间多个线性调频脉冲(Chirp)信号的多个参数的方法,并给出了简单的性能分析。与文献中的方法相比,本文的方法避免了多维搜索,计算量小,有利于实时实现。模拟结果表明,本文的方法能在较低的信噪比下,较为准确地估计出多个线性调频脉冲信号的多个参数。
A method of multiple parameters estimation for multiple chirp signals is proposed, a brief performance analysis is also described. Compared with references, the computational load of the method is more attractive, it is favorable to realize for real-time. It is no need for multiple-dimensions search. The results of simulation show that the method can accurately estimate multiple parameters of multiple chirp signals under the lower ratio of signals-to-noise.
