Improved target detection in doppler tolerant radar using a modified hex coding technique

Abstract

In every corner of the globe, nations want to improve the monitoring mechanism of the country, so that no one can enter their territory in an unwanted manner easily. Well-known equipment, called Radar, is commonly used for monitoring. However, only a small amount of work is done to monitor multiple moving targets in the presence of Doppler. This important issue diverts the attention of the research community away from working on this platform. In the present literature, the merit factor (MF) is improved by increasing the amplitude of the main lobe. However, these particular approaches did not attach more importance to the effects of noise side peaks of fast moving targets. The drawback of noise peaks masks slow-moving targets and cannot be clearly seen by the radar receiver. As a result it reduces the performance of the Doppler radar system. In this paper, an approach is presented which not only improves multiple moving target detection, but also reduces the energy of code generation. This approach is simple and effective in detecting multiple moving targets at the desired Doppler. The presented technique is called Improved Target Detection in Doppler Tolerant Radar Using a Modified Hex Coding Technique. MATLAB is used to formalize the results by simulation.
