Radar Signal Processing Techniques for Distance and Velocity Measurement

This video outlines a comprehensive analysis of radar signal processing, focusing on the design and operational principles behind radar systems for distance and velocity measurement. It begins with the fundamental structure of a radar system, emphasizing the roles of the transmitter, receiver, and the digital signal processing (DSP) unit. The video meticulously explains the process of generating and receiving chirps, the significance of chirp repetition for velocity measurement, and the critical role of signal processing techniques in extracting range, velocity, and angle of arrival information from radar signals. Through a detailed mathematical framework, it demonstrates how to calculate the maximum range and velocity that can be measured, along with the resolution of these measurements. The narrative also introduces the application of Fast Fourier Transform (FFT) in analyzing the frequency content of received signals to infer distance and speed, culminating in a discussion on system design considerations for achieving desired measurement accuracies and resolutions.
