Analysis and Simulation of Coherent Integration Process for Target Echo Signals

This project conducts analysis and simulation of coherent integration process for target echo signals using MATLAB. Throughout this process, we will thoroughly examine each step of target signal accumulation and demonstrate the actual procedure through simulations. The implementation involves using MATLAB's signal processing toolbox functions such as fft for frequency domain analysis and cumsum for cumulative summation operations.

We will first introduce the fundamental concepts and characteristics of target echo signals, then explain the principles and methodologies of coherent integration. Key algorithms include pulse compression techniques and Doppler processing using phased array system toolbox functions. Subsequently, we will detail MATLAB's applications in the target accumulation process, providing relevant simulation results with code snippets showing parameter configuration and signal processing workflows. The simulation will demonstrate how coherent integration improves signal-to-noise ratio through phase-aligned signal summation. Finally, we will summarize our research findings and discuss potential future enhancements and application domains, including possible extensions to radar signal processing and sonar systems using adaptive filtering techniques.
