一个跟踪器型烟火源的辐射调制系统。辐射源既不发射气体,也不发射粒子体,装在旋转的导弹上。导弹用地面接受装置沿光路制导。该系统的目的是为了改进发射的信号/背景噪声比。辐射发射源装在导弹尾部,要使其辐射沿导弹旋转放出,就像跟踪其轨迹一样,而且要用一与导弹一起旋转的极化泸波器泸波。系统中还有另一个极化泸波器,装在地面接收装置的光路中,它的作用是拾取第一泸波器所放出的环状极化辐射,并以两泸波器之间所形成的相对转速为频率使该辐射得以正弦调制。其结果是,发射源所放出的调制信号与未调制的背景噪声之比大为增大,并可随时处理传递信号以对导弹进行光学指令制导。
Radiation modulation system for a tracker type pyrotechnic source. Radiation sources neither emit gas nor emit particles, mounted on rotating missiles. The missile is guided along the optical path by a ground receiving device. The purpose of this system is to improve the transmitted signal / background noise ratio. Radiation sources are installed at the rear of the missile, to make its radiation along the missile rotation release, just as track its trajectory, but also with a missile with the rotation of the polarizer wave. There is another polarization filter in the system, which is installed in the optical path of the ground receiving device. Its function is to pick up the circularly polarized radiation emitted by the first wave filter and to form The relative speed of rotation is the frequency of sinusoidal modulation of the radiation. As a result, the ratio of the modulated signal emitted by the transmitting source to the unmodulated background noise is greatly increased and the transmitted signal can be processed at any time to optically instruct the missile.
