Comprehensive Simulation of General PD Radar System

This program represents a comprehensive simulation framework for general Pulse Doppler (PD) radar systems, incorporating essential signal processing stages such as pulse compression, Moving Target Detection (MTD), and Constant False Alarm Rate (CFAR) detection. The simulation models the operational principles of radar systems and the functionality of individual modules, enabling effective evaluation of radar performance under various environmental conditions and operational scenarios. During the pulse compression phase, the program simulates received radar pulse signals and processes them using matched filtering techniques to enhance range resolution and improve target signal-to-noise ratio. The implementation typically involves cross-correlation operations between transmitted waveforms and received echoes. In the MTD processing stage, the simulation implements Doppler processing algorithms to detect moving targets amidst background clutter. This typically involves Fast Fourier Transform (FFT)-based Doppler filtering across multiple pulses to distinguish targets based on their velocity characteristics. The CFAR module simulates adaptive threshold detection mechanisms that maintain constant false alarm rates in varying noise environments. The implementation may include cell-averaging CFAR algorithms that dynamically set detection thresholds based on surrounding noise statistics. By executing this simulation program, users can gain comprehensive insights into radar system operational principles and module functionalities, thereby enhancing their understanding and application of modern radar technology. The code structure allows for parameter modifications to analyze system performance under different configurations and scenarios.
