针对红外导引头研发和测试的需要,提出了一种对四元红外探测系统信号源建模的方法,即计算机仿真与硬件平台相结合的方法。通过仿真模型的计算获得目标运动、干扰弹投放和探测器噪声等动态信息,并由硬件平台实时产生对应的四路脉冲信号,可较好的模拟真实环境下位标器的输出,为验证导引头跟踪与抗干扰算法的有效性提供测试平台。阐述了四元红外探测系统的工作原理、信号源的软件仿真及硬件实现方法。

To satisfy development and test of infrared seeker, a modeling method of four-element infrared detection system was propose, which was achieved by combination of computer simulation and hardware platform. The dynamic information generated by model calculation was composed of target movement, release of jamming projectile and noises, the hardware platform generated four real-time pulses which simulated output of the coordinator in real environment. A test-platform was provided for seeker to verify and modify the algorithms of tracking and anti jamming. The working principles of four-element infrared detection system and the method of software simulation and hardware implementation were described.
