基于多波束抛物面天线的高动态目标角捕获

Angle Acquisition of Dynastic Target Using Multi-beam Parabolic Antenna

为了解决临近空间高动态目标的角度引导捕获问题,提出了基于多波束抛物面天线的高动态目标角捕获方法与基于质心求解的目标指向成像技术。对于系统检测概率、检测时间进行了理论分析与仿真验证,指出理论分析结果与实际系统存在不一致性。搭建了简化的中频测试平台,对不同信号形式进行了测角成功概率的测试,为遥外测综合测控自跟踪系统的建设提供了技术支撑。

To solve the problem of high dynamic target angle guiding and acquisition in near space, a method based on multi-beam parabolic antenna is proposed as well as pointing image technique based on barycenter solver. According to the analysis and simulation of detection probability and time consumption, it is pointed out that the theoretical result doesn＇t coincide with the practical. A simplified IF test platform is set up, on which guiding success probability is tested for different kinds of modulation. The research supports the construction of TT＆C tracking sub-system.
