By combining the differential equation with the according guidance law, a relative trajectory equation is set up which will help to study the characteristic of trajectory.

Shortcomings in terminal counter-trajectory of the torpedo in service are discussed based on the analysis of tor- pedo re-attacking trajector and the necessity to solve this problem is pointed out.

To obtain wide field of view and high resolution ratio, the calibration method and procedure of ballistic camera with multi-CCD system are presented, and the principle and composition of calibration system are also introduced.

There are many ways for controlling ballistic camera and collecting various time data.

An Optimization Design for Phase Controller of Revolution Shutter in Trajectory Camera Based on DPLL;

To delete false intersection results produced by multiple trajectory cameras when they measure the multiple near ground coplanar targets with basic intersection method, a method for deleting false targets and improving the intersection accuracy with partial least squares multiple factors regression analysis is presented.

The system is developed to digitize the trajectory camera photo plates and analyse the images accurately and automatically to replace the manual work which is poorly efficient.
