摘要: 該文提出了一種估計空間多個線性調(diào)頻脈沖(Chirp)信號的多個參數(shù)的方法，并給出了簡單的性能分析。與文獻中的方法相比，本文的方法避免了多維搜索，計算量小，有利于實時實現(xiàn)。模擬結果表明，本文的方法能在較低的信噪比下，較為準確地估計出多個線性調(diào)頻脈沖信號的多個參數(shù)。Abstract: 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.
