Abstract :
A digital distance simulator is developed to fulfil static accuracy test for a multi-frequency continuous-wave (MFCW) ranging system. The Baseband Phase Shift Simulation Method is presented to solve the conflict between high resolution and long range. With the adoption of the Direct Digital Synthesizer (DDS), the simulator can achieve the relative resolution of 0.015% with low complexity and high flexibility
