Abstract

The invention discloses a method for testing a mono-pulse radar horizontal direction diagram based on the pulse sorting technology. The method mainly comprises the following steps that S1, according to a set sampling frequency, signals of radar to be tested are sampled so that a sampling point sequence can be obtained; S2, a pulse threshold is calculated; S3, a pulse sequence is determined and the pulse time, the pulse width and the pulse amplitude of each pulse are calculated; S4, pulse width sorting is conducted on the pulse sequence; S5, pulse time interval sorting is conducted on the pulse sequence; S6, a rotating period of the radar is calculated; S7, point supplementation is conducted on the pulse sequence; S8, the radar horizontal direction diagram is formed. The method has the advantages that the radar horizontal direction diagraph can be tested under the condition that the radar does not stop working, sampling is conducted on the received signals at the high sampling frequency, so that the accuracy of an antenna direction diagram is improved, and fault diagnosis and maintenance of the mono-pulse radar are facilitated.

Description

technical field [0001] The invention relates to a method for testing a horizontal pattern of a monopulse radar, in particular to a method for testing a horizontal pattern of a monopulse radar based on pulse sorting technology. Background technique [0002] With the continuous innovation and development of technology, the demand for radar in modern warfare has increased dramatically, which has led to an increase in the need for radar overhaul and maintenance. At the same time, the further use of domestic civilian radar has caused the lack of radar test instruments and professional technical personnel at domestic radar stations at all levels. Therefore, how to quickly, accurately and efficiently judge the status of radar and assist in fault location analysis has become an extremely urgent and important task. question. The new radar test system came into being, and the portable radar opening tester is an important achievement of the development of the new radar test system. T...
