Title:
METHOD FOR OPTIMIZING WAVEFORM OF LINEAR FREQUENCY MODULATED CONTINUOUS WAVE UNDER MIMO SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/022683
Kind Code:
A1
Abstract:
Provided is a method for optimizing a waveform of a linear frequency modulated continuous wave under a MIMO system. Said method comprises: adding random phases to different emission waveforms in each pulse of a linear frequency modulated continuous wave, the random phases forming a random phase matrix H; constructing an evaluation index for evaluating the waveform quality; constructing a cost function F according to the evaluation index; and searching, by means of a pattern search method, for a corresponding value of the random phase matrix H when the minimum value of the comprehensive index cost function F is obtained, and replacing the random phases of the emission waveform with same, so as to obtain an optimized emission waveform.
