The Error Analysis of the Chirp Radar Waveforms Based on DDS Technology
Shuang Zhao, Yue Yu · Applied Mechanics and Materials · 2014
Based on the chirp signal radar using DDS technology, the waveform of the wideband chirp signal source is analyzed. By analyzing the system error model, the method that selecting the chirp steps in accordance with the digits of DDS phase truncation is proposed. It reduces the system errors caused by the phase truncation.
