Description

technical field [0001] The digital image injection simulation technology of the present invention particularly relates to an SDI-based injection image algorithm testing device. Background technique [0002] As the "eye" of the missile, the tracking system plays a pivotal role and has important strategic significance in target strike. The tracking system can extract the position information and attitude information of the target from the video signal, and use the extracted position information and attitude information to drive the servo mechanism to complete the transformation of the space field of view of the tracking system. The tracking effect of the tracking system mainly depends on the reliability of the tracking algorithm. In order to test the reliability of the tracking algorithm, the simulation of the tracking system must be involved. [0003] The simulation of the tracking system mainly includes two types: radiation simulation and injection simulation. The latter g...
