红外制导半实物仿真及目标模拟器研究

导弹仿真技术为红外制导导弹提供了一个精确、可控和可重复的试验条件,而半实物仿真作为仿真技术的一种,除了可以提高系统的研制质量以外,还可使无法准确建立模型的实物直接进入仿真回路,并可直接检验制导控制系统各部分功能.利用红外目标模拟器系统,可为导引头性能测试提供一种方便、可行、价廉的实验手段,可提供不同气象条件、不同背景下的不同目标的红外特征,以便较全面地测试导引头的各种性能,并可节省大量的实验经费.针对红外制导导弹的半实物仿真系统进行了概述,并结合具体示例介绍了红外制导导弹半实物仿真系统组成.详细论述了一种带一个目标和两个干扰的点源红外目标模拟器的原理与实现.

Infrared Seeker Hardware-in-the-Loop Simulation and Target Simulator

Missile simulation technology offers accurate, controllable and repeated test condition for missiles guided by infrared seeker. As a kind of simulation technology, hardware - in - the - loop simulation can not only improve the design quality of whole system, but also test the functions of control and guidance system directly. Infrared target simulator provides a convenient, feasible and cheap test method. Different infrared characters obtained from different targets under different weather conditions and different backgrounds make it convenient to test the performance of infrared seeker completely. At the same time, much outlay for the experiment is saved. Besides, the onstitution of infrared seeker hardware - in - the - loop simulation system is described. A kind of infrared target simulator with one target and two interferences has been developed.
