Liu Changchang,Xu Hao,He Xuezhi,Chen Weidong +3 more
- 03 Dec 2010
TL;DR: This paper proposes a novel imaging method, named Spherical Coordinates Method (SCM), so as to get higher resolution and better imaging quality, a broader, more uniform and compact coverage in wavenumber domain is required and this can be achieved through the following three methods: increasing the number of the receivers, making use of the motion information and optimizing the disposition of the receiver.

Chen Weidong,Xu Shanjia,Wang Dongjin,Liu Falin +3 more
- 14 Sep 2000
TL;DR: In this article, the effects of frequency sweep nonlinearity on the range performance were discussed based on the criteria of determining the Carson bandwidth, an approximate relationship among the range resolution, the target range delay and the mean square root of the nonlinear frequency errors was presented at small phase modulation index.

ISAR imaging of fast-moving target based on FRFT Range Compression
Yin Zhiping,Fu Zhen,Wang Dongjin,Chen Weidong +3 more
- 01 Nov 2007
TL;DR: A new reconstruction algorithm is proposed, which use Fractional Fourier Transform (FRFT) instead of DFT to implement the range compression, and indicates that the new algorithm can avoid the range dispersion and achieve refocused ISAR image effectively.

A Study on Scatter-Wave Jamming for Countering SAR
Li Tao,Chen Weidong,Lu Guanghua,Wang Dongjin +3 more
- 18 Apr 2007
TL;DR: This paper analyzes the fixed offsets of the false target by using the scatter-wave jamming mode, and then presents a method to synthesize a false target with given offsets both in range and azimuth direction.

LFM signal detection using the origin moment of fractional spectrum
Yin Zhiping,Zhang Dong-chen,Chen Weidong,Wang Dongjin +3 more
- 08 Dec 2008
TL;DR: In this paper, a new detector based on the origin moment of fractional spectrum (OMFrS) for LFM signal is proposed, which is established as a detector via the proof of the equivalence between the fourth order OMFrS and the modulus square detector of RAT.
