Primary Study On Real Time Control In Fire Counterattack System Of Super-Short-Range Antimissile

The development of PGW ( Precision Guided Weapon ) impulses the antimissile technology and one of the signs is the appearance of super-short-range antimissile. This paper gives the primary discussion and research in introducing the embedded system into super-short-range antimissile project , choosing real time systems, configuring the corresponding hardware and primary studying on the system platform for the real time control system of fire counterattack system in super-short-range antimissile.This paper firstly introduces some basic concepts of embedded system and ERTOS(Embedded Real Time Operating System), then on software chooses μC/OS-II for final researching by analyzing and comparing ERTOSs of four, which are the real time operating systems of charging free with open source code and considering of the actual need, on hardware chooses SAMSUNG S3C44B0X chip (which is one kind of the most extensive embedded microprocessor at present - ARM ) and adds some relevant hardware circuit , and then successfully transplants μC/OS-II onto the object board and gives the validation for the transplantation. Finally , it primarily fulfills the hope of real time control for the fire counterattack system and accomplishes three tasks: the simple communication with the radar detecting system , trajectory calculation with the method of looking up in tables and driving the driver of servo system, and establilshes the framework of the real time control system on the whole.
