Phase-Coded Time and Frequency Separation for Unambiguous Velocity Measurement

DESCRIPTION

This document explores the concepts of phase-coded time separation and frequency staggering in radar signal processing. It introduces T1 and T2 as critical parameters for achieving unambiguous velocity (Va) with the relationship Va ~ 1/Tu, where Tu is defined as Tu = 1/(T2 - T1). The cleared range (Ra) is also defined as Ra ~ 2Tu = T1, establishing a framework for utilizing these techniques in radar applications. Through this approach, improved measurement accuracy in velocity and range can be achieved, thereby enhancing radar system performance.
