Abstract
In todays world the defense security system facing most important interesting issue for the doppler radar is the detection of multiple moving targets attacks. But the process of detection and ranging target fails because the shadow of fast-moving targets (noise) may hide the slow-moving targets, which may lead a serious damage in the battlefield environment. Hence, measurement of these parameters (i.e., range and resolution) of target is a challenging issue. Considering these challenges, current research trend concentrates on enhancement of Merit Factor (MF) as well as Signal-to-Noise Ratio (SNR) of the radar system. In this paper, a novel approach has been proposed, namely, trellis code generation using quad code sequence. This method improves the Merit Factor (MF) of the main lobe; on the other hand, it reduces the side spikes of the noise amplitude below 80 dB caused by fast-moving attacks during target detection process. Thus enhanced SNR acheived by creating multiple clear windows at different Doppler’s (frequency shift) with respect to target range. We have validated our approach using Matlab.
