Enhance Multiple Moving Target Detection in Doppler-Tolerant Radar Using IRAESC Technique

Abstract

Nowadays, nation’s power is gauged in terms of technology to keep an eye on the enemy movements in their vicinity. Hence, there is a need to work for the advancement of detection and tracking technology. For this purpose, the Doppler-tolerant radar fulfills the purpose of detection of multiple moving targets. So such systems needed to be strengthened in terms of precision in detection of multiple moving targets. The art of work of such radars focuses much toward stationary and slow moving targets. In this perspective, abundant work has been done to improve the figure of merit of autocorrelated signal in which transmitted and received signals are operated, thereby increasing the accuracy in detection of multiple moving targets. However, such systems fail to detect multiple moving targets under Doppler shift by suppression of reflection from small moving targets due to noise peaks of the autocorrelated signal. In this paper, we provide a digital coding technique to enhance the probability of target detection by the use of ASCII code to IR system called Indian Radar ASCII EX-OR System Code Technique (IRAESCT). This approach authenticates the position of the target and on the same time, it reduces the noise spikes below the threshold limit, which results in the creation of clear windows to help the multiple moving target detection with respect to desired Doppler. We validate our results using MATLAB.
