Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as figure 1 As shown, the method for avoiding mutual interference in the radar system of the present invention comprises the following steps:

[0026] S100. Acquire an intermediate frequency signal of the i-th radar in the radar system.

[0027] In this embodiment, the intermediate frequency signal is obtained through the following steps:

[0028] The i-th radar sends the FMCW signal, receives the echo signal, mixes the echo signal and the sent FMCW signal to obtain the radar intermediate frequency signal, and identifies the target in the intermediate frequency signal;

[0029] Alternatively, the i-th radar forms an FMCW signal in the transmitting circuit, but does not send the FMCW signal, but only receives it, and mixes the received signal and the FMCW signal to obtain a radar intermediate frequency signal.

Abstract

The invention relates to a method for avoiding mutual interference in a radar system. The method comprises the steps of acquiring an intermediate frequency signal of an ith radar in the radar system, wherein the maximum effective frequency of the intermediate frequency signal of the radar is gi<max>; performing interference analysis on the intermediate frequency signal; calculating a new working frequency starting point f'i which can not be interfered; changing the working frequency starting point of the ith radar into f'i so as to avoid the interference with other radars. The method disclosed by the invention can be used for ensuring that a plurality of radars in the radar system do not need to stagger the time of transmitting signals; meanwhile, radio frequency signal frequency spectrums of the plurality of radars can be mutually overlapped, so that each radar does not need to use an independent frequency band, thus greatly improving the frequency spectrum utilization efficiency, and ensuring that more radars working simultaneously can be supported on a certain frequency spectrum.

Description

technical field [0001] The invention relates to a method for avoiding signal interference in wireless communication, in particular to a method for avoiding mutual interference in a radar system. Background technique [0002] At present, in the process of using multiple radars in the radar system, it is usually the time when multiple radars stagger the transmission signals, that is, a time period is divided into multiple time sequences, and different radars work in different time sequences. In this way, the radar system The number of radars supported at the same time is limited. [0003] In addition, each radar in the radar system can also use a separate frequency band, and these frequency bands do not overlap. In this way, a large number of frequency bands need to be occupied, resulting in low spectrum utilization efficiency. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide...
