Abstract

Embodiments of the present invention relate to a radar data calibration method, a dot trace quality evaluation method, and a storage medium. Provided by the corresponding embodiment of the radar data calibration method: segment the initial track information to obtain the segmented track information, filter the segmented track information to obtain the filtered track information, and obtain the filtered track information according to the filtered track information and After the ADS‑B data information determines the judgment result, the target track point is selected according to the judgment result, and the technical solution of the calibration result is determined according to the target track point and point track information, which avoids a large number of residual clutter points in the prior art The technical disadvantages of the radar data are efficiently and accurately calibrated, and the technical effect of safe and reliable calibration results is obtained.

Description

Radar data calibration method, dot trace quality assessment method, storage medium technical field Embodiments of the present invention relate to the technical field of radar data processing, and in particular to a calibration method and point trace of radar data. Quality assessment methods, storage media. Background technique [0002] With the continuous development of science and technology, the application of radar is also more and more extensive. [0003] The radar irradiates the target by transmitting electromagnetic waves and receives its echoes, thereby obtaining the distance, azimuth, height, etc. of the target. information. In this process, due to various factors such as the geographical environment, a large number of clutter signals may be generated, resulting in a large number of false signals. Generation of false dots. If the clutter false traces are not effectively suppressed in the data processing stage, the clutter traces will eventually produce Genera...
