| Airborne fire control system is an indispensable part of aircraft combat.Its performance directly determines the accuracy of weapon ammunition projection and the operational effectiveness of aircraft.The airborne fire control system software controls the operation of the system.Designing software that meets the overall performance specifications of the system is the work that needs to be done on this topic.In order to realize the real and effective launch of the missile,the working principle of the X-type glide bomb is studied.Combining the overall technical indicators and functional requirements of the fire control system,a matching fire control process plan and simulation process plan are proposed to improve the operational efficiency.In order to meet the high performance requirements,a high-speed digital signal processor(DSP)is used as the core processor for data calculation,In order to improve the reliability and security of software,a structured design approach is used to implement the software architecture.In order to improve the accuracy of placement,GNSS is used to locate the position and speed of the aircraft,and the geodetic technology is studied for navigation and attack envelope calculation to guide the aircraft to accurately deliver.In order to meet the system function requirements,the basic graphics rendering algorithm,character modulo method and non-volatile flash memory technology in image processing are studied,so as to realize software data communication,navigation and attack parameter dynamic display,fire control guidance,flight data recording,fault processing,system detection and other functions.This paper first introduces the overall design of the airborne fire control system,introduces the hardware design and layout in combination with hardware resource conditions,analyzes the software functions and data requirements according to the overall technical requirements,and introduces the memory allocation and software boot process,Completed the entire software architecture design.At the same time,combined with the current state of technology development and implementation,the modular design is introduced,and the key module design and implementation forms are introduced,and relevant theoretical analysis and research are carried out,and the program refinement is completed.Finally,the GNSS simulator is used to simulate the flight path of the aircraft,and the airborne fire control system is simulated and tested.Through the analysis of the recorded data,the system operation status and results meet the overall technical input requirements and indicators. |
