Implementation of Combined Binary Phase Coded and Linear Frequency Modulated Signals with Visualization Techniques

This documentation explores MATLAB implementation techniques for generating and visualizing hybrid signals that combine binary phase coding with linear frequency modulation. The implementation involves creating a phase-coded sequence using discrete phase shifts (typically 0 and π radians) and superimposing it on a linear frequency modulated chirp signal characterized by a continuously varying frequency. Key MATLAB functions include chirp() for LFM generation and custom phase coding algorithms for signal combination.

We further demonstrate the computation and visualization of the ambiguity function, which evaluates the time-delay and Doppler shift resolution capabilities using 2D correlation techniques. The spectral analysis section covers Fourier transform implementations (fft()) with windowing functions and proper power spectral density normalization. These methodologies provide comprehensive insights into signal processing techniques for radar and communication systems, with practical code examples showing parameter optimization and visualization best practices.
