RADAR SIGNAL PROCESSING DEVICE WHICH USES A NONLINEAR FREQUENCY MODULATION WAVEFORM, CAPABLE OF BEING TRANSMITTED BY THE DIGITAL SYNTHESIS, AND A METHOD THEREOF

摘要

PURPOSE: A radar signal processing device and a method thereof are provided to effectively prevent the energy loss of a reception signal by generating a nonlinear frequency modulation signal waveform.;CONSTITUTION: A frequency modulation part(110) outputs a specific control signal, an address value, and a delta frequency value for a nonlinear frequency modulated signal waveform. A frequency synthesis part receives the address value and the delta frequency value according to the specific control signal from the frequency modulation part. The frequency synthesis part outputs the nonlinear frequency modulation signal waveform by using a direct digital synthesis method. A counter part(111) executes a timing count for the entire control. A data storage part(113) stores a delta frequency by using a window function.;COPYRIGHT KIPO 2011
