Abstract

The invention discloses an aviation altimeter application efficiency detection method based on dynamic continuous detection, and belongs to the technical field of aviation equipment application efficiency detection. After the transmission pulse envelope signal is adjusted by the height factor, the received pulse envelope signal is formed, and after carrier modulation, up-conversion and power amplification, it is output to the radio frequency input port of the aviation altimeter through the radio frequency cable; through the data bus and the aviation altimeter The data ports of the altimeter are connected, and the altimeter value of the aviation altimeter is extracted to obtain the altimeter error data; by constructing the altimeter error matrix, the application efficiency state value of the aviation altimeter is determined according to the principle of maximum membership. The solution of the present invention can implement dynamic continuous detection, and can detect the practical application ability of the aviation altimeter under the comprehensive consideration of terrain, interference and other factors, and improve the reliability of the detection result.

Description

technical field [0001] The invention relates to an application efficiency detection method of aviation equipment, in particular to an application efficiency detection method of aviation altimeter equipment based on dynamic continuous detection. Background technique [0002] Aviation altimeter is a radio device used to measure the altitude of aviation platforms. The measured altitude information is not only used to indicate the altitude of aviation platforms, but also used for radio navigation and positioning, fire control system parameter binding, etc. Therefore, whether the altimeter can provide accurate altimetry data is very important for aviation platforms. [0003] Because the ground static detection method cannot meet the needs of the altimeter measurement range and high measurement accuracy, dynamic detection is mainly used for the detection of aviation altimeter. There are two main methods. One is to carry out flight measurement, but this method has high detection ...

AI Technical Summary

Problems solved by technology

This method is likely to cause large fluctuations in altimeter data, low accuracy and high precision, and it is impossible to implement dynamic continuous detection, and can only be used for functional qualitative detection;

[0005] Second, in the existing detection methods, when the analog altimeter receives 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 caused by different terrain conditions. The impact from the above is not consistent with the actual use scene of the aviation platform altimeter, and the reliability of the test results is low;

[0006] Third, in the existing detection method, when the analog altimeter receives the pulse signal, the influence of complex electromagnetic environment factors on the altimeter is not considered, so the anti-interference ability of the altimeter pulse signal in the transmission process cannot be detected, which is different from that of the aviation platform altimeter. The actual application scenario does not match, and the actual application performance of the aviation altimeter cannot be tested;

[0007] Fourth, in the existing detection methods, most of the detection results use 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 terrain conditions. , Use the influence of the environment and other factors to test the actual use ability of the altimeter
