Accuracy assessment of aerial miss distance using optical measurement
Aiming at the requirement of high accuracy assessment of aerial target miss distance,an evaluation model of the miss distance measurement accuracy in the same frame is established.According to the characteristics of the same frame target measurement and the correlation between the miss distance measurement,the error composition of the miss distance measurement is analyzed.According to the measurement method of miss distance in the same frame and the correlation of error transfer in the weapon system,the optical rendezvous position error is analyzed and the space miss distance error is established.At the same time,the error transfer coefficient of the measuring equipment to each measurement value and the contribution degree of each measuring equipment to the three-direction miss distance in space are calculated.The total error of aerial miss distance is determined.The proposed method can provide a theoretical basis for the optical measurement evaluation of the aerial miss distance.
