In this embodiment, the phased array radar 11 is a two-dimensional radar, the radar control interface has stored a topographic map and an elevation map of the current target area in advance, and when the radar detection unit 1 detects an object, the type of the object can be predicted according to the prestored topographic map and information such as the movement speed, the position, the distance and the like of the object, so as to predict whether the object is a detection target.

It should be noted that the target information acquired by the radar detection unit 1 includes longitude, latitude, elevation, speed, type, and the like of the target. In addition, since the phased array radar 11 is a two-dimensional radar, when the target is a ground target, the radar detection unit 1 can acquire accurate target azimuth information and elevation; however, when the target is an aerial target, the radar detection unit 1 can only obtain accurate azimuth information of the target and cannot obtain accurate elevation information of the target, in this case, the type of the target can be pre-judged according to a topographic map of a target area, the elevation of the target can be pre-judged according to the type of the target, and then the pitch angle of the photoelectric imaging unit is manually adjusted by an operator according to the elevation.
In some embodiments, the optoelectronic control terminal has two operation modes, one is an automatic tracking mode, and the other is a semi-automatic tracking mode.
The automatic tracking mode is suitable for the situation that the target is a ground target, in the mode, the photoelectric control terminal can calculate the direction and the pitching angle of the target at the current position of the photoelectric imaging unit 2 according to the station position of the photoelectric imaging unit 2 and the received target information, and the photoelectric control terminal sends an adjusting instruction to the photoelectric turntable according to the angle so as to drive the photoelectric imaging unit 2 to turn and point to the target and shoot a target image.
