Objectives: To Design Doppler tolerant radar codes to enhance multiple moving targets. Methods/Statistical Analysis: In this paper we present a novel mathematical approach to improve the target detection in Doppler tolerant radar. The presented approach in this paper is called Re-Sampling Binary Hex Code Windowing Technique (RSBHCWT). This approach not only increases the amplitude of main lobe, but also decreases the amplitude of side lobs to create multiple windows at desired Doppler. We use mat lab to validate our results through simulation. Findings: We developed a windowing approach that can detect multiple moving targets. Application/Improvements: The presented model is useful in military applications. Our approach is on top of oversampled PTM code by creating number of windows with respect to desired Doppler’s.
