探测和识别攻击目标时,往往需要联合使用红外被动传感器和单脉冲雷达主动传感器,使用这种联合装置,就可以从单纯反射雷达波的目标和单纯辐射出能量而使红外传感器响应的目标中,识别所需既反射又辐射的人为目标。这种联合装置还能用来确定辐射目标的距离。此外,由于光学法可得到更高的角分辨力,所以,在反射-辐射目标的情况下,在所接收到的反射信号和辐射信号中取一种信号调制另一种信号,就可以使雷达有效倾斜距离内的角分辨力和距离分辨力都比纯反射目标时的好。但是,真正要把这种多路传感装置做出来,就必须要有有效的方法使被动传感器的响应与主动传感器的距离时间响应相关,这样就能确定被动探测的辐射目标的距离和方向。上面提出的调制法是直接控制正析象管的视场,从而使红外传感器的光轴不断随所
When detecting and identifying attack targets, it is often necessary to jointly use infrared passive sensors and monopulse radar active sensors. With this combination device, from the goal of simply reflecting the radar wave and simply radiating energy to make the infrared sensor respond to the target, Identify the need for both reflective and radiating human targets. This combination can also be used to determine the distance to the target of radiation. In addition, since the optical method can achieve higher angular resolution, in the case of a reflection-radiation target, taking one kind of signal from the received reflection signal and the radiation signal to modulate the other kind of signal enables the radar The angular resolution and range resolution of the effective tilt distance are better than those of the purely reflective target. However, to really make such a multiplexed sensing device, there must be an effective way to relate the passive sensor’s response to the active sensor’s time-dependent response so that the distance and direction of the passive-detected radiation target can be determined. The modulation method proposed above is the direct control of the field of view of the CRT, so that the optical axis of the infrared sensor constantly
