Analysis of the Impact of Airborne Multi-antenna Radar Power Architecture on Weight

Multi-antenna phased array radar is widely used in airborne detection, and the weight of its power system is affected by the number of antenna and power architecture. Based on the morphological differences of secondary power supply, the power architecture is divided into independent unit architecture, independent module architecture and distributed architecture. By analyze the weight composition and characteristics of power system in multi-antenna radar, the applicable scenarios of various architectures are obtained, and the influencing mechanism of antenna number on power weight is demonstrated. Finally, based on typical airborne fire control radar, the specific weight composition of power system of various architectures in single-antenna radar and three-antenna radar is compared, and the specific effect of antenna number on power weight is obtained.
