Abstract:

In order to test and evaluate the features and performance of a kind of radar single processor, this article provides a multi-parallel automatic test system design .It is on the basis of PCI bus combined with Lab Windows/CVI, Database and Direct Digital Synthesis technology. It has achieved a radar signal processor which can provide radar echo simulation, high stability ADC acquisition clock and multi-channel type pulse input. Furthermore it is focused on the completion of the multi-type radar signal processor bus test and analysis of key performance. Also it can provide quantitative test results and analysis combined with typical products. Finally,it has completed the verification of the effectiveness of the test system.
