Research and Design of in-situ Test Method for Active Phased Array Radar

The airborne active phased array radar has become the typical symbol of the fourth generation fighter, and is one of the most important weapons and equipment in the information war. With its large number of armed forces, the problem of falling performance index has gradually aroused the attention of equipment maintenance support personnel, and phased array radar has the characteristics of high equipment value, difficulty in disassembly and maintenance, and high use intensity, so it is necessary to study the in-situ test and maintenance method. In this paper, an active phased array radar in-situ testing method is presented, which can be used to test the performance of the transmitting channel, receiving channel and direction map of airborne active phased array radar, and the maintenance suggestions are put forward. The application shows that this method can effectively improve the detection efficiency of radar. Enhance the maintenance support capability of the user unit.
