摘　　要：空间目标探测对测量雷达威力提出了更高的要求,当雷达功率孔径积增大到其极限值时,需要挖掘其他潜力来提高雷达作用距离。文中介绍了超导接收前端的组成、原理和特点,通过对雷达威力的分析和计算,比较了不同噪声系数条件下,雷达作用距离与发射功率、天线口径的关系,将噪声系数极低的超导接收前端应用于雷达可以显著提高其作用距离。The detection range distance of measurement radars will be increased for spatial target.Other potential will be found to enhance the radar detection range when radar power aperture product reached the maximum.The compose,principle and characteristics of receiver with superconducting front end are introduced.According to the radar formula,detection range emission power and the aperture of the antenna are compared with different noise cofficient.The detection range of the measurement radar is increased remarkably if a receiver with superconducting front end is applied.
