Abstract:In order to explore the hidden nodes in the trajectory of the spacecraft with directivity, according to the characteristics of the enterprise, an adaptive measurement method for spacecraft hidden target points based on MEMS lidar measurement technology is proposed. The discrete radar filter is used to collect the upper position data in the laser measurement process, and then the radar measurement performance index is obtained to promote the moderate decline of the directivity measurement coefficient. On this basis, based on the motion characteristics of the spacecraft target, the maximum likelihood of the eigenvalues ??is estimated, and then the relevant measurement indicators are combined to establish the feature model of the spacecraft target, which suppresses the downward trend of the target point fretting frequency. Using the stereo vision processing results of hidden targets, the measurement points most suitable for MEMS laser radar are selected, and the proportion of hidden targets of spacecraft is measured under the condition of this, and the measurement method of hidden target points of spacecraft under MEMS lidar measurement is completed. The spacecraft trajectory is simulated in the RCS platform. With the application of MEMS lidar measurement technology, the target point fretting frequency is increased, the directivity measurement coefficient is decreased, and the hidden target node is effectively measured.
