Problems solved by technology

[0004] These existing methods can generate fewer signals, and generally only two signals can be generated. When the number of signal channels increases, the correlation performance and fuzzy characteristics drop sharply, which cannot meet the requirements of practical applications.

Abstract

The present invention relates to a method and device for generating MIMO radar signals based on frequency hopping technology, the method comprising: generating a plurality of chirp signals with incompletely equal amplitudes and incompletely equal initial frequencies; and applying the chirp signals to MIMO radar The frequency hopping duration on the array elements is used to generate MIMO radar signals.

Description

technical field [0001] The invention relates to the technical field of MIMO radar, in particular to a method and device for generating MIMO radar signals based on frequency hopping technology. Background technique [0002] MIMO (Multiple-Input Multiple-Output) radar can improve system performance, so it is receiving more and more attention. [0003] A good MIMO radar signal needs to satisfy large time-bandwidth product, low peak-to-average ratio, good ambiguity characteristics and correlation performance. The existing methods for generating MIMO radar signals mainly include: using the correlation matrix of the transmitted signal to make the energy launch to the ideal range angle; the method of generating the signal by considering the characteristics of all designed signals and their correlation matrix; optimizing The method of MIMO radar ambiguity function to generate signal. [0004] These existing methods can generate fewer signals, and generally only two signals can be ...
