Description

technical field [0001] The invention relates to an application performance detection device for aviation equipment, in particular to an application performance detection device for aviation altimeter equipment. Background technique [0002] The aviation altimeter is a radio device used to measure the altitude of the aviation platform. The measured altitude information is not only used to indicate the altitude of the aviation platform, but also used for radio navigation positioning, fire control system parameter binding, etc. Therefore, whether the altimeter can provide accurate altimetry data is very important for aviation platforms. [0003] There are mainly two types of detection devices for aviation altimeters: ground static detection devices and dynamic detection devices. Since the ground static detection device cannot meet the needs of the altimeter's altimeter range and high precision, the dynamic detection device is mainly used to detect the performance of the aviati...

Problems solved by technology

This type of detection device is likely to cause large fluctuations in the altimeter measurement data, low measurement accuracy and low dynamic continuous detection, and can only be used for functional qualitative detection;

[0005] Second, in the prior art, when the detection device simulates the altimeter to receive the pulse signal, it is the echo signal under the simulated ideal channel condition, and does not consider the irregular reflection, absorption, multipath and other factors of the pulse signal in different terrain states The impact brought by it is inconsistent with the actual use scene of the aviation platform altimeter, and the reliability of the test results is low;

[0006] Third, in the existing technology, when the detection device simulates the altimeter to receive the pulse signal, it does not consider the influence of complex electromagnetic environment factors on the performance of the altimeter, so it cannot detect the anti-interference ability of the altimeter pulse signal in the transmission process, and the aviation platform The actual application scenarios of the altimeter do not match, and the actual application performance of the aviation altimeter cannot be tested;

[0007] Fourth, in the existing technology, most of the detection results of the detection device adopt the method of visually observing the altimeter instrument panel to subjectively judge the working status and performance of the height. Only functional detection can be carried out, and quantitative index detection cannot be carried out, let alone comprehensive The influence of factors such as terrain state and use environment to test the actual operation ability of the altimeter
