Centralized phased-array antenna FPGA program upgrading method and system

Abstract

The invention discloses a centralized phased-array antenna FPGA program upgrading method and system, and relates to the technical field of phased-array antennae, and the method comprises the following steps: building a phased-array antenna program upgrading system; after the phased-array antenna program upgrading system is powered on, the upper computer sends a handshake instruction to the signal processor; the signal processor forwards the handshake instruction to the wave control mother board FPGA; after the wave control mother board FPGA is powered on, a bootstrap program is loaded, and the bootstrap program receives a handshake instruction and returns a handshake success signal to the upper computer; the upper computer issues an instruction for upgrading the user engineering program data, and the wave control mother board FPGA upgrades the user engineering program data according to the received instruction; re-electrifying the wave control mother board FPGA and the configuration chip; and executing a hot start command, switching to the upgraded and updated user engineering program, and enabling the phased-array antenna to operate normally. According to the method, the phased-array antenna is upgraded and updated without uncovering the phased-array antenna, disassembling the whole machine, welding interfaces and the like, so that time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of phased array antennas, in particular to a method and system for upgrading a centralized phased array antenna FPGA program. Background technique [0002] Phased array antenna refers to an antenna that changes the shape of the pattern by controlling the feeding phase of the radiating element in the array antenna. Controlling the phase can change the direction of the maximum value of the antenna pattern for beam scanning purposes. In special cases, the sidelobe level, the minimum position and the shape of the entire pattern can also be controlled, such as obtaining a cosecant square pattern and performing adaptive control on the pattern. When the antenna is rotated mechanically, the inertia is large and the speed is slow. The phased array antenna overcomes this shortcoming, and the scanning speed of the beam is high. Its feeding phase is generally controlled by an electronic computer, and the phase changes...
