Coherent Single Range Doppler Interferometry Algorithm For High-Speed Spinning Targets 2D Imaging

摘要：

This paper focuses on the narrow band radar imaging for high-speed spinning targets.Based on the timefrequency characteristic of the echoed signal,a novel coherent spectrogram redistribution method,coherent single range Doppler interferometry (CSRDI),is proposed,which is of high resolution and robust even in the case of the low signal-to-noise ratio. The spinning rate error is also taken into consideration and an estimating approach based on the focal entropy is proposed. The validity of the approaches is confirmed by Numerical simulations.
