technical field [0001] The present invention relates to the technical field of airborne photoelectric reconnaissance, tracking and monitoring, in particular to an airborne dual-band photoelectric wide-area reconnaissance and tracking device and method, which can realize rapid imaging search and stable tracking of sea surface and ground targets, greatly improving the Its effectiveness for use in search and rescue at sea and on the ground. Background technique [0002] Facing the increasing number of search and rescue tasks at sea, it is expected to significantly improve the search and rescue capabilities of sea and ground targets through the airborne photoelectric detection equipment equipped on the airborne platform. At present, the airborne photoelectric detection equipment that can be equipped with unmanned aerial vehicles, helicopters, and medium-to-high-speed fixed-wing aircraft generally adopts a photoelectric turret with a spherical structure, equipped with visible lig...

AI Technical Summary

Problems solved by technology

However, the shortcoming of the swing-broom scanning is that when the aircraft is moving forward, because the line of sight of the photoelectric imaging detection equipment moves left and right perpendicular to the course of the aircraft, the distance from the detected target is constantly changing, resulting in the detection of the equipment. The imaging resolution of the image changes continuously with the left and right scan angles

However, the disadvantage of this method is that the system is required to adjust the scan rate of the left and right movement of the line of sight at all times to avoid missed scans.

[0008] 4. Another important issue associated with performing aerial reconnaissance is motion compensation

The disadvantage is that electronic motion compensation is only applicable to charge-coupled devices (CCDs), and current area array infrared focal plane devices and complementary metal-oxide-semiconductor (CMOS) devices cannot use this technology

[0012] Therefore, the disadvantage of the currently used motion compensation technology is that it only compensates for the image blur caused by the forward motion of the aircraft and the left and right scanning motion perpendicular to the aircraft heading. Heavy weight and high cost
