Time-Domain Compact Range Measurement System for Radar Targets
Building scheme and developing procedures of a measuring system for radar targets were introduced. Theory of time domain measurement was studied. Sampling Oscilloscope was used for measurement in compact range for the first time. Structure of the system and operating flow for the measurement were presented. Programs for controlling of the oscilloscope and turntable as well as data processing were developed, based on which entire measuring software of UWB compact range was achieved, including measurement of radar cross-section, polarization scattering matrix and microwave imaging. FFT and windowing technique as well as digital filtering were used to transform data from timedomain to frequency-domain and to improve the accuracy. Idea of virtual instrument was used in the program. Finally, some data measured and processed by the system were presented, which proves performance of the system.
