Investigation of the Continuous Wavelet Transform Method for Use with Late Time Response Analysis of Concealed on Body Threat Objects

Abstract- investigation of the use of continues wavelet transform (CWT) method to late time response analysis for detecting on body concealed threat objects proposed in this paper. The transient backscattered mechanisms of on body concealed weapons target signatures are studied using the wavelet analysis technique in which signal processing algorithm is developed and the Morlet wavelet applied to extract and analyses the re-radiated transient response of concealed targets. Experimental work was done by using simple and complex objects such as wire and handgun, Wavelet analyses of backscattered data from various objects are presented, the results show that the Continues wavelet transform (CWT) has the ability to detect and discriminate between the hidden-on body objects.

Characteristics of Tapered Slot Antenna for on body buried Objects detection

The detection of human body worn concealed metallic objects based on the late time response (LTR) method is one of the great challenges. Successful LTR extraction to identify the target signature and its correct interpretation requires UWB antenna, which can cover the frequency of the fundamental (lowest) complex natural resonance (CNR) of the target(s) under detection. A flat gain UWB tapered slot antenna with operating bandwidth of 0.25-3GHz to cover the lowest CNR frequencies designed and fabricated. Antenna tests made in an anechoic chamber to provide complete back scattering and signal radiation control. The results showed that the fabricated antenna has relative flat gain from about 0.3GHz to just over 3GHz with distortion less narrow pulse transmission.

An approach for on body concealed weapon detection using Continuous Wavelet Transform

Continues Wavelet Transform (CWT) applied to the scattering response of on body concealed weapons. A series of experiments were conducted to test the system which involved on and off body objects such as, knives, handheld guns. Experimental results illustrated the success of the approach in analyzing the LTR signature. Spectral response for every target could be seen as a distribution in which the energy level and life-time depended on the target material and geometry and gives powerful information of the target unique signature
