Radar Pulse Compression Simulation

This code provides multiple implementation approaches, including a dechirp processing method and a fast convolution simulation technique. The dechirp processing method employs image rotation and translation operations to eliminate skewness, making images easier to process and recognize through geometric transformation algorithms. For the fast convolution simulation technique, it utilizes Fast Fourier Transform (FFT) based convolution to accelerate computation speed, significantly improving image processing efficiency and accuracy by reducing computational complexity from O(n²) to O(n log n). The implementation likely involves cross-correlation operations in frequency domain and inverse FFT for result reconstruction. Additionally, the code includes other optimization approaches to accommodate different application scenarios, providing flexibility for performance tuning and algorithm selection based on specific requirements such as real-time processing constraints or precision demands.
