Problems solved by technology

Since the above two types of altimeters generally use analog working methods, there are many discrete devices such as resistors, capacitors, transistors, and operational amplifiers, which not only cause the equipment itself to be large in size, heavy in weight, and low in measurement accuracy, but also difficult to integrate with other altimeters. System integration and synthesis, so a digital radio altimeter is urgently needed to solve this problem

Abstract

The invention provides a digitalized radio altimeter comprising a radio frequency assembly unit, a low frequency amplification unit, a low frequency servo loop circuit unit and a microprocessor monitoring circuit unit that are all orderly connected; information data is input into the low frequency amplification unit from the radio frequency assembly unit, the obtained information data is transmitted to the low frequency servo loop circuit unit by the low frequency amplification unit, then the information data is transmitted to the microprocessor monitoring circuit unit by the low frequency servo loop circuit unit, and the radio altimeter is advantaged by high measurement precision and strong function expandability.

Description

technical field [0001] In particular, the invention relates to a digital radio altimeter. Background technique [0002] The current radio altimeter mainly has two systems, one is the pulse system, and the other is the FM continuous wave system. Since the above two types of altimeters generally use analog working methods, there are many discrete devices such as resistors, capacitors, transistors, and operational amplifiers, which not only cause the equipment itself to be large in size, heavy in weight, and low in measurement accuracy, but also difficult to integrate with other altimeters. System integration and synthesis, so a digital radio altimeter is urgently needed to solve this problem. Contents of the invention [0003] The purpose of the present invention is to provide a digital radio altimeter for the deficiencies of the prior art, which can well solve the above problems. [0004] In order to meet the above-mentioned requirements, the technical solution adopted by...
