Problems solved by technology

[0004] The program update is generally to connect the unit to be programmed with the main control device through the programming cable, so that each unit needs to mount the programming cable to the radar digital unit when the program is updated, because the radar is generally large in size, and the programming ports are generally in the array On the surface, the programming cable used is generally long, it is laborious and time-consuming to mount the cable, and the programming stability is not high

Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] In order to meet the needs of quickly updating large array digital radar software, the technical problem solved by the invention is to realize the rapid update of the radar front unit program and the fast switching of application programs through the point-to-point communication interface between the radar front unit and the signal processing system.

[0024] Please also refer to figure 1 , figure 2 and image 3 , the specific implementation process for implementing application updates is as follows:

[0025] The first step is to use the programming cable to load the default program to the non-volatile memory or load the default program and the application program to the non-volatil...

Abstract

The present invention discloses a method for parallel refreshing of programs of a radar array digital unit. The radar array digital unit comprises a communication port, a field-programmable gate array (FPGA) and a nonvolatile memory. The nonvolatile memory is divided into three sections: a default program area, an application program area and an electronic label area. In the default program area, a default program only can be loaded by a configuration cable and is mainly in charge of read-write operation of the nonvolatile memory through the communication port. In the application program area, an application program is loaded, and functions of the radar array digital unit are mainly implemented in the application program. In the electronic label area, specific information of each radar array digital unit is written in and read out when the default program or application program is in operation, and the information cannot be destroyed by power failure and program refreshing. When a system is powered on, the FPGA is started, enters the default program, then is automatically restarted to enter a certain application program after a short stay in the default program or is restarted to enter a certain application program after receiving a command from the communication port, and then starts to work normally.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a parallel refreshing method of a radar array digital unit program applied to the large array digital radar industry. Background technique [0002] The digital phased array radar has beam electronic scanning capability, is flexible and fast, and can realize multi-target interception, tracking, and self-adaptive capability. The scale of the existing digital radar array is getting bigger and bigger, and the flexibility of its beam scheduling is getting bigger and bigger. [0003] For digital array radar, due to the large number of array units, high integration, and relatively large volume, a program update of the radar system requires a program update for each digital unit, which often consumes a lot of time, especially for system development and joint debugging. In this stage, the program of the front unit needs to be changed frequently. The current solution is to ...
