Abstract

The invention discloses a method for dynamically estimating the track of an electronic reconnaissance satellite target. The method is proposed according to the difference in the distribution variance of the measured moving target position data projected in different navigation directions, including: generating all possible navigation directions of the moving target Projection base; project the measured two-dimensional position data on each projection base to achieve dimensionality reduction; calculate the data variance of the position data after projection, and use it as the judgment condition for estimation; compare the variance of all the heading projection data, and select the one with the largest variance Projecting the base heading as the heading estimation of the moving target, taking the projected target data as the preliminary estimation result of the track; and making multi-point average of the preliminary estimation result, and the averaged track estimation result as the final output result.

Description

technical field [0001] The invention relates to a data processing algorithm and its hardware realization, in particular to a track estimation data processing algorithm for electronic reconnaissance satellite identification target and its realization device. Background technique [0002] Electronic Reconnaissance Satellite (Electronic Reconnaissance Satellite) is a reconnaissance satellite used for reconnaissance, intercepting electromagnetic signals sent by enemy radar, communication and weapon telemetry systems, and measuring the location of the signal source. Limited by satellite computing capabilities, reconnaissance satellites are only responsible for intercepting the original information of enemy targets. The original information is transmitted to the ground by satellites, and the final intelligence information is completed by ground computing equipment. [0003] Electronic reconnaissance satellites can be divided into radar intelligence reconnaissance satellites and co...
