Design of universal test equipment of pulse radar altimeter

Abstract:

Virtual instrument technology can improve flexibility and expansibility of test system. A design method of universal test equipment for pulse radar altimeter is introduced in this paper. Based on computer and standard instruments，by using Dynamic Link Library(DLL) of standard instruments control built by LabVIEW via Visual C++, the parameters of pulse radar altimeter such as working voltage，transmitting frequency，receiving frequency，movement sensitivity and transmitting power can be tested，displayed，printed and stored. The test results can be queried in the future. By increasing notes in parameter list and upgrading DLL，it is convenient to measure other types of pulse radar altimeter with this test equipment using parametric design and database modeling technology.
