Problems solved by technology

The existing technology uses embedded software to write a single fixed number in different TR components for management. The three-coordinate phased array antenna using this management method needs to confirm the TR component number first when debugging and field maintenance support, and carry out relative The corresponding software configuration can meet the requirements of the system, and the interchangeability and maintainability of TR components are poor.

Embodiment

[0022] A three-coordinate phased array radar antenna TR component number automatic identification method, the method includes the following steps:

[0023] Step 1: Connect the numbered control line at each TR component of the three-coordinate phased array radar antenna;

[0024] The numbering control line is composed of N single wires, and each single line outputs high and low levels to indicate 1, 0. By configuring the high and low levels of the numbering control line, it shows a string of binary numbers, which is equal to its corresponding TR The decimal position number of the component. The value of N can be greater than or equal to log 2 An integer of n, where n is the number of TR components. In order to save costs and not waste wires, the value of N can be greater than or equal to log 2 The smallest integer of n, where n is the number of TR components.

[0025] Such as figure 1 As shown, the number of TR components on the antenna array is 12 for example:

[0026] At the instal...

Abstract

The invention provides a method for automatically identifying serial numbers of TR assemblies of a three-dimensional phased array radar antenna. The method comprises the following steps that (1) each TR assembly of the three-dimensional phased array radar antenna is connected with a serial number control line; (2) after being powered on, each TR assembly reads information of the serial number control line of itself, and serial number identification is conducted; (3) each TR assembly calls control words corresponding to the series number of itself so as to achieve beam control, receiving branch attenuation control and TR assembly self-inspection. The method has the prominent advantages that the TR assemblies of the three-dimensional phased array radar antenna interchange, debugging performance and working efficiency of a system can be improved, and maintainability of the system can be substantially improved.

Description

Technical field [0001] The invention relates to the field of three-coordinate phased array radar antenna TR components, in particular to a method for automatically identifying the number of a three-coordinate phased array radar antenna TR component. Background technique [0002] Three-coordinate phased array radar antenna elevation beam scanning is realized by TR component phase shifting. When the antenna beam points to a certain angle, the phase shift amount of the TR component at different positions of the array is different; in addition, the receiving antenna array amplitude is weighted to reduce the sidelobe level The program-controlled attenuation of the receiving branch is also controlled by the TR component, and the attenuation is related to the installation position of the TR component front. Therefore, the three-coordinate phased array antenna needs to perform number management on the TR components to achieve beam control and receiving branch attenuation control. The pr...
