Abstract

Abstract:

A novel detection method dealing with range walking for the broadband radar target using high resolution range profiles (HRRP) is proposed. The proposed detector, the iterative generalized likelihood rate test (iGLRT), is derived by estimating the signal steering vector through a bi-iterative algorithm (BIA) after constraint range alignment and estimation of the length and position of the target. Furthermore, global convergence is analyzed and the constant false alarm rate (CFAR) property is proved. Finally, experimental results for measured data of two planes illustrate that the proposed algorithm leads to at least 1.4dB improvement for 80％ detection possibility compared with the conventional scatter density dependent generalized likelihood rate test (SDD-GLRT).

Key words: broadband radar target detection, high resolution range profiles, constant false alarm rate, detectors, iterative methods
