Abstract

An altimeter detector belongs to the technical fields of detection measurement and test, and solves problems of single detection object, and inconsistent detection means and standards on different altimeters of an existing altimeter detector. The altimeter detector of the present invention uses a DSP digital signal processing circuit as a core device; the DSP digital signal processing circuit outputs attenuation control signal and delay control signal to a height simulation circuit, so as to control the height simulation circuit to generate a plurality of equivalent height radiofrequency signals corresponding to a plurality of heights to the altimeter; the DSP digital signal processing circuit acquires voltage current signal of the altimeter through an A / D converting circuit, and acquires digital signal of the altimeter and control signal output to the altimeter through an altimeter interface circuit. Application of the altimeter detector of the invention can realize detection on a plurality of altimeters, substantially increase altimeter test efficiency and bring convenience to test and maintenance of the altimeter.

Description

technical field [0001] The invention belongs to the technical field of detection, measurement and testing, and its sub-field is the static test of performance parameters of weapon components, in particular to a radio altimeter performance automatic detection device. Background technique [0002] With the development of altimeter technology, the altimeter detection technology has gradually matured.
