It provides valuable data and result to passive orientation of moving air target under the situation of li.

In this paper, the electromagnetic characteristic of a space moving object was researched and the movement of object was visual simulated.

Simulation of infrared radiation of air target;

Threat value of air target is that it can evaluate damage degree of attacking ground(surface) target in command and control of air defense system.

A parameter estimating method for air targets by fire control system of air defense weapon is presented in allusion to the characteristics in this paper.

Based on the requirements of fleet anti-air combat,a real time threat assessment of maneuvering aerial targets has been established in this paper.

Differentiating model of aerial targets type integrated with targets tactical characteristics;

Detection and recognition of aerial targets based on the Bubble wavelet function and GVF Snake model;

Grey cluster decision making way for the threat ordering of aerial targets;

Multi-class classification of air targets based on support vector machine;

There are two detecting and tracking modes for air targets,initiative mode and passive mode.

The vehicular step-track paraboloid antenna,which is stabilized in the inertia space by compensating the disturbance angle,has been widely used to track air targets.
