Two-dimensional Length Extraction of Ballistic Target from ISAR Images Using a New Scaling Method by Affine Registration [PDF]
, 2014 The length of ballistic target is one of the most important features for target recognition. It can be extracted from ISAR Images. Unlike from the optical image, the length extraction from ISAR image has two difficulties. The first one is that it is hard

Sparse Representation Denoising for Radar High Resolution Range Profiling [PDF]
, 2014 Radar high resolution range profile has attracted considerable attention in radar automatic target recognition. In practice, radar return is usually contaminated by noise, which results in profile distortion and recognition performance degradation.

An Efficient Kernel Optimization Method for Radar High-Resolution Range Profile Recognition
EURASIP Journal on Advances in Signal Processing, 2007 A kernel optimization method based on fusion kernel for high-resolution range profile (HRRP) is proposed in this paper. Based on the fusion of l1-norm and l2-norm Gaussian kernels, our method combines the different characteristics of them so that not ...
