In far interception,it can greatly reduce the equal-time miss distance which induced by ignoring the disturbed factors on conditions when the initial orbit-change stage is short and the guidance system is sufficient accuracy.

Vector miss distance measurement based on range and velocity target tracking;

Measurement algorithm of scalar miss distance based on narrow pulse;

Spacecraft Miss Distance Test Method Based on a Single Radar;

The system real-time disposes and judges video image,obtains undershoot values and relatively distortion of vessel by combining two measure results.

Computer video judge system incepts two video signals, video collection and video disposing adopting parallel fashion, real-time disposes video image and judge, obtains undershoot values and relatively distortion of vessel by combining two meas.

This application not only acquires the realtime measurement of target,missile and relative velocity,but also completes the real-time measurement of MDI vector.

In order to meet the real-time demands of some vector miss distance mesurement systems,a fast vector miss distance estimation algorithm is presented in this paper.
