基于STM32和FPGA的PPI信息采集与复现系统设计

在实际作战过程中,平面位置显示器(PPI)是雷达装备显示空情信息的重要手段.为解决某高炮指挥员对空情信息无法实时获取的问题,结合某高炮火控系统PPI信息的特点,提出并设计了一种PPI信息采集与复现系统.该系统基于FPGA设计了一种软性状态机模块来控制MAX196的数据采集,以STM32F407为系统枢纽控制PPI信息采集与传输,利用OpenGL形象复现PPI显示信息.实验结果表明,该系统可以对多通道、多类型信号进行实时采集,采集误差小,实时性强,性能稳定,实现了PPI信息的远程重显,为空情信息的远距离采集、传输与显示提供了一套可行性方案.

Design of PPI information acquisition and representation system based on STM32 and FPGA

In the process of actual combat,the PPI display is an important means of radar equipment display air situation.In order to solve a certain anti-aircraft gun commander to the problem of unable to real-time access to air situation information,combined with the characteristics of some fire control system PPI information,this paper presented and designed a PPI information acquisition and representation system.This system is based on the FPGA to design a kind of soft state machine module to control the data acquisition of MAX196,hub for STM32F107 to control PPI information acquisition and transmission,using OpenGL image retrieval PPI display information.The experimental results show that the system can real-time acquisition of multi-channel,multi-type signals,the sampling error is small,strong real-time performance,stable performance and realize remote PPI information show,for air of long-distance information acquisition,transmission and display provides a set of feasible solutions.
