Airborne radar multi-target detection data and truth value matching method

Abstract

The invention provides an airborne radar multi-target detection data and truth value matching method, which comprises the following steps of: 1, acquiring data, taking airborne radar data of bus data of a local aircraft as original input of a radar detection value, taking inertial navigation data of bus data of other aircrafts as original input of a truth value of aircraft position information, and acquiring the truth value of the aircraft position information; forming a radar detection data set and a position truth value data set of the target according to the parameter indexes; step 2, establishing a coordinate system by using the local aircraft, taking inertial navigation data of airborne bus data of other aircrafts, establishing a relative position information set of the local aircraft and other aircrafts, and using the information set as a true value; and step 3, calculating the matching degree of the target radar detection position and the target truth value by using a dynamic time warping algorithm. And step 4, preferably selecting a matching result according to the matching degree. The method can be used for a tester to realize matching work of a detection target and a real target for the airborne radar in a multi-target environment, and has a key significance for evaluating the positioning accuracy of the airborne radar.
