Based on the characteristics of air-defence radar in service,this paper analyses the difficulties,key techniques that are to be solved.

Battlefield Existence Effectiveness Evaluation for ground surveillance radar;

Based on the requirement for the radar disposition and mobile conservation,exerting course affecting radar existence effectiveness have been divided into three procedures,anti-reconnaissance,anti-destroying and repairing,according to the characteristics of ground surveillance radar.

This paper presents the guide lines to select the optimum operating frequency for the new generation of air surveillance radar.

This paper presents the analysis method of air surveillance radar s coverage.

This paper presents the detailed analysis and calculation for different factors that effect the range, azimuth and height measurement accuracies of air surveillance radar,and gives a lot of error calculation formulas.

Design and realization of radar intelligence simulation system;

In this paper,a radar intelligence fiber transmission system is implemented by using CPLD, and its simulation waveforms are also given.

This paper introduces the method and flow of treating these radar intelligence.

Since radar information is commonly transmitted via serial ports in radar information processing systems, its transmitting quality must be considered.

On the basis of effect-cost-ratio increment analysis after covering radome over radar antenna, some designing criteria for the ground information radar radome are discussed in order to obtain the optimal effect-cost-ration.

This paper studies the adaptability to highland environment for information radar.

The basic problems in cruise missile detection u sing ground based information radar are analyzed based on the brief introduction about the main features of the cruise missile.
