摘要
某自行高炮进行瞄准线和射击线稳定需进行车体姿态的测量,在车体停止情况下对装备火控系统的检测离不开车体姿态信号的模拟。其姿态测量装置输出的姿态量是粗精结合的正余弦旋转变压器信号,该信号可采用数模转换得到。通过直接数字频率合成技术(DDS)产生正弦激励信号,以仿真方式采用地形面匹配技术产生车体姿态信号数字量,用乘法型D/A转换器实现激励信号和姿态信息的合成,得到满足正余弦变化规律的车体姿态信号。
Stabilization of the aiming line and the firing line in a type of AA gun needs to measure bodywork attitude information.When bodywork is motionless,the detection of fire control system was dependent on the simulation of bodywork attitude information. The attitude data output from the attitude measuring device were sine-cosine resolver signals,and they can be generated by D/A converter.Stimulus signals were produced by means of direct digital synthesis technique,and bodywork attitude digital information was generated by terrain match technique in simulation mode.The two former signals and the required attitude information were synthesized by use of multiplying D/A converter so as to acquire bodywork attitude signals that meet changing rule of sine-cosine.
