Method of Chirp-subpulse Stepped Frequency Signal Range Profile Based Wavelet Transform at Low Altitude

摘要：

Feasibility of chirp-subpulse stepped frequency signal to implement high range resolution at low altitude is educed through analysis of its amplitude and frequency spectrum in this paper.Method of chirpsubpulse stepped frequency signal range profile based wavelet transform with nicer locality and approximation on time-frequency domain is brought forward.Compared with traditional IDFT,range resolution capability is improved further on multipath problem by using this method,and thus makes locating and tracking for targets at low altitude penetration more feasible.
