Simulating Terminal Guidance Radar Operations Using MATLAB SIMULINK

This implementation demonstrates how to simulate terminal guidance radar operations using MATLAB's SIMULINK toolkit. The process begins with understanding fundamental radar principles including signal transmission, target detection, and echo processing. Within SIMULINK, we construct a block diagram model that replicates the radar's operational chain - from waveform generation and antenna radiation pattern simulation to signal reception and processing algorithms. Key model components include configurable parameter blocks for transmitter power (typically modeled using dBm units), receiver sensitivity thresholds, beam scanning rates, and antenna characteristics. The simulation incorporates environmental factors through additive white Gaussian noise blocks and interference sources to mimic real-world scenarios. Signal processing subsystems employ matched filtering techniques and Fast Fourier Transform (FFT) blocks for target parameter extraction. During simulation execution, scope blocks visualize intermediate signals while MATLAB function blocks calculate target metrics including range (via time-delay analysis), velocity (using Doppler frequency shift algorithms), and azimuth angles (through phased array beamforming simulations). This modeling approach enables comprehensive performance evaluation, allowing engineers to optimize parameters like pulse repetition frequency and integration time before hardware implementation. The modular SIMULINK architecture facilitates easy integration of advanced features such as electronic counter-countermeasures (ECCM) and adaptive beamforming algorithms.
