非完整表面角反射器的RCS特性研究

Research on RCS characteristics of corner reflector with incomplete surface

摘要:

角反射器对雷达电磁波有极强的反射回波特性，可模拟舰船、装甲车等军事目标。金属角反射器在使用过程中因锈蚀、油污等原因造成角反射器表面破损，造成其性能严重下降。本文分别研究了角反射器反射面不同的破损面积和破损数量条件下雷达散射截面积（RCS）特性，金属角反射器RCS值随反射面破损数量增多和面积增大快速降低，可有效量化评估角反射器剩余电磁波反射能力

Abstract:

Corner reflectors have strong reflection echo characteristics for radar electromagnetic waves, which can simulate military targets such as ships and armored vehicles. The surface of the metal corner reflector is damaged due to rust, oil pollution and other reasons during the using process, resulting in a serious decline in its performance. This paper studies the Radar Cross Section（RCS） characteristics of the corner reflector under different damaged areas and damage numbers are respectively studied. The RCS value of the metal corner reflector rapidly decrease with the number and areas of the damage of the reflecting surface increase, which can effectively quantitatively evaluate the residual electromagnetic wave reflection capability of the corner reflector.
