在红外目标背景仿真中，所要模拟的目标往往不只一个。其中，应包括实际目标的所有有用信息。如机身的主要特性、天空背景以及对导弹的人工干扰等。这些信息往往是利用光学方法独立生成的，各独立源最终复合后再提供给导引头进行接收，从而保证导引头跟踪目标的真实性。在多目标元复合过程中，不同的目标元有着不同的光谱特性及不同的能量特性。介绍了网纹镜及光缆的多目标复合方法及应用原理，其中，网纹镜复合法为反射式，适用于宽谱段，但工艺难度大；光缆复合法简单，可使系统小型化。两种方法都具有很好的实际效果。

There may be more than one object to be simulated in the system of infrared obje ct background simulation. All useful information of real object are included, such as main properties of the plane body, sky background, man-made interferenc e to missiles and so on. The information is produced independently by optical m ethod, then supply independent sources compounded for homer to receive, which as sures the reality of homer tracing the targets. Every object has different spec trum characteristic and energy characteristic in multi-objects compounded. T wo kinds of the multi-objects compounding method and applied theory are introdu ced. Cellular-mirror compounding method is the reflection type. It can be appl i ed to the wide spectrum, but technique is very difficult. Optical cable compoun d ing method is easy, which minimizes size of the system. Both methods have satis fied practical results.
