Broadband amplitude monopulse system secondary radar monopulse angle measurement visualization method

Abstract

The invention, which relates to the radar signal processing field, discloses a broadband amplitude monopulse system secondary radar monopulse angle measurement visualization method. The method comprises the following steps that: a monopulse device sends information of a response signal and target data to terminal equipment according to a predetermined format; the terminal equipment receives the information of the response signal and the target data and then loading and generation of static data are carried out; loading is carried out by employing a graphical mode and an antenna directional diagram is displayed; and a monopulse secondary surveillance radar off-boresight angle (OBA) table is generated by the antenna directional diagram. Because the loading is carried out by employing the graphical mode and the antenna directional diagram is displayed, a main beam shape, the width, sigma and delta channel phase distribution situations of the antenna directional diagram can be displayed visually, so that it is convenient for engineering personnel to arrange a monopulse parameter under a corresponding antenna feed system. Besides, it is convenient to realize amplitude monopulse system secondary radar monopulse angle measurement function verification and a precision analysis under a broadband condition; a requirement for maintenance equipment by a system is reduced; high flexibity is realized; and maintenance cost can be effectively controlled.

Description

technical field [0001] The invention relates to the field of radar signal processing, in particular to a method for visualizing the angle measurement of a secondary radar monopulse in a broadband amplitude monopulse system. Background technique [0002] The general method for debugging and testing secondary radar equipment in the amplitude monopulse system is to place the monopulse secondary radar on the wireless joint test platform (the position of the interrogation equipment and the response equipment should be calibrated on the joint test platform), and the wireless joint test platform should be calibrated. Try it out. The monopulse secondary radar transmits the interrogation signal, and receives the reply signal answered by the answering device, calculates the distance and azimuth data of the target, and compares the azimuth of the monopulse angle measurement with the real azimuth of the target to detect the effect of the monopulse angle measurement. By analyzing the re...

However, the response information data generally has a large amount of data. When analyzing the data, it is not only necessary to decipher the data packet, but also to convert the unit and base system; direct manual analysis of the data is not only inefficient, but also not intuitive enough, and it is difficult to analyze the single pulse It is very difficult to monitor the whole process of secondary radar work, especially when looking for occasional problems, it is very difficult to analyze clues in massive data
