Abstract

The invention provides a radar time synchronization method and device. The method comprises the steps: determining the current coordinate and direction angle of each radar in a first rectangular coordinate system constructed in a target region, and constructing a second rectangular coordinate system of each radar; obtaining a reflection position track of each radar, the reflection position track being a time sequence of position coordinates of each strongest reflection point reflected by electromagnetic waves of the radar in a second rectangular coordinate system according to a preset track moving the corner reflector; converting the reflection position track of each radar into a conversion position track under a first rectangular coordinate system; according to the at least two preset time delay amounts, determining an optimal normalization correlation coefficient of a conversion position track corresponding to a target radar in the at least two radars and each to-be-measured radar, further determining a to-be-adjusted time delay amount of each to-be-measured radar, and performing time delay processing on the radars based on the to-be-adjusted time delay amount. According to the scheme, time synchronization of multiple radars can be realized.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a radar time synchronization method and device. Background technique [0002] Radar technology has been widely used. In daily life, we can use radar to realize weather forecast, traffic control, navigation and many other applications. [0003] At present, when radar is used to detect and track targets in an area, multiple radars are usually used to work simultaneously. However, when the system time of multiple simultaneous working radars is not synchronized, accurate fusion processing cannot be performed based on the data collected by each radar, so that accurate detection of targets cannot be achieved. Contents of the invention [0004] Embodiments of the present invention provide a radar time synchronization method and device, which can realize time synchronization of multiple radars. [0005] In a first aspect, the present invention provides a radar time synchroniza...
