Muti-component Linear FM Signal Detection Based on Clustering
Linghuan Wang · Radio Engineering of China · 2006
Linear FM(LFM)signal is a commonly-used pulse compression radar signal in modem radar system.The clustering algorithm was introduced to get the number of the pinnacles in the result of the time-frequency analysis and Radon transform of the multi- component LFM signal,and to finish the detection of the components of the LFM signal.Meanwhile,an approach called Near Zero Mean,for reducing the point number of the input data-set for clustering,was proposed to improve the computation efficiency.The simulation results depict that this approach is efficient for the detection and parameter estimation of the multi-component LFM signal with low SNR.
