一种实用的目标散射特性动态测量系统

A Practical Dynamic Measurement System of TargetScattering Characteristics

介绍了一种实用的目标散射特性动态测量系统及其标定方位。该系统在现有精密坐标测量雷达上增加了目标特性测量支路，实时地跟踪采集目标反射回波的幅度和相位特性数据、目标坐标数据以及雷达工作参数。系统采用数控衰减、高线性度中放和Ｉ、Ｑ正交双通道，具有较高的采样率和较宽的测量波门。

In this paper, a practical dynamic measurement system of radar target scattering characteristics and its calibration methods are described. The system is added to a precious coordinate measurement radar to sample the data of amplitude and phase of target scattering wave. The system has digital control attenuator, high linear IF magnifier, I/Q channels, high speed A/D converters and wide measurement gate.
