    摘要:

    为了全天时、全天候、隐蔽性探测海面舰船目标,提出将高分辨率综合孔径微波辐射计作为星载微波辐射无源探测系统,用于探测海面舰船目标。提出一种新方法用于定量化评估微波辐射无源探测系统探测目标的能力;建立系统关键指标、目标微波辐射截面和探测距离间的关系,分别推导微波辐射无源探测系统的探测概率方程和探测距离方程;开展仿真分析和机载验证实验,其结果均表明高分辨率星载综合孔径微波辐射无源探测技术探测海面舰船目标是可行的。高分辨率星载微波辐射无源探测系统可作为我国天基预警体系的重要补充。

    Abstract:

    To detect the large-scale vessel targets in the whole day, all-weather and concealed, the synthesis aperture microwave radiometers with high resolution are proposed for the first time as a space-borne microwave thermal radiation passive detection system, which is used to detect the vessel targets on the sea. A novel method is proposed to quantitatively evaluate the detection capability of a space-borne microwave passive detection system. The relationship between system’s main specifications, the microwave radiation cross section of the target and the detection distance is established. The detection probability and the detection distance are derived, respectively. Simulation analysis and air-borne experiments are also carried out. Both simulation and experimentalresults demonstrate the feasibility of the space-borne synthesis aperture microwave thermal radiation passive detection technology with high resolution to detect the large-scale vessel targets. The synthesis aperture microwave radiometers with high resolution can be used as an important complementary system for space-based warning.
