Problems solved by technology

[0002] The detection probability is an important index to measure the radar detection capability. Usually, the detection probability is to make the target aircraft fly at a radial and constant speed relative to the radar, and divide it into equal intervals along the flight route. The number of discovery points and observation points, calculate the discovery probability of the target, and draw the discovery probability-distance curve, so as to obtain the detection distance map under various discovery probability conditions, but on the one hand, the batch number and track data of the target track data Information such as latitude and longitude is different from the target intelligence data reported by the radar. On the other hand, the data rate of the track of the flying target is different from the data rate reported locally by the radar.

Abstract

The invention provides a radar discovery probability assessment method and device based on air situation data. The method comprises the following steps: gridding a radar detection airspace to generate a detection airspace resolution cell grid; performing track time cross matching and detection power cross matching on the radar report track and the information center fused track, and preliminarily judging that the radar report track and the information center fused track are the same target track; performing track interpolation matching on the same target track, and performing accurate matching on the track reported by the radar and the track fused by the information center; interpolating the precisely matched fused track to obtain a target full track matched with the radar report track data rate, and calculating the radar discovery probability of each resolution cell grid on the target full track. According to the invention, the fused data can be accurately matched with the track data reported by the radar, and the fused track data is processed to generate a target full track matched with the data reported by the local radar.
