Positioning and monitoring system, and positioning and monitoring method

The invention relates to the technical field of a method for correcting radar measurement errors and particularly discloses a positioning and monitoring system and a positioning and monitoring method.Pure radial motion is performed through a cooperative target, and a deviation angle between the point trace detected by radar and the GPS point trace is observed to correct an angle error. The delayof the GPS point trace sending only generates an error in the radial distance, so that the error between the 0 degrees of the radar and the true north angle can be accurately corrected. Pure tangential motion is performed through the cooperative target so that two arcs with a topocentric center as the center should be formed on the interface of the radar monitoring operation terminal, and the distance difference between the two arcs is the radar distance error that needs to be corrected. The delay of the GPS point trace sending only generates the error in the angle, so that the correction of the radar distance precisio
