In order to defend national sovereignty and safeguard national territories, territorial waters and airspace, it is necessary to conduct timely inspections, monitoring and intelligence information collection on disputed areas, track suspicious targets and obtain evidence. Under this background, various detection platforms have became the standard equipment of reconnaissance aircraft, patrol aircraft, marine surveillance ships, coast guard ships and other carriers. They can operate round the clock, suitable for reconnaissance, surveillance, search and rescue, target locating, identification, tracking and navigation.
Due to carrier’s movement, posture changes, mechanical vibration and such case, the effectiveness and stability of opration of the detection platform system installed on the aircraft or ship hull will be directly affected. Therefore, in practical applications, a detection platform is designed to be an independent part with respect to the carrier. The detection platform itself can control the stability of the attitude by INS, thus effectively isolating the disturbance from the carrier’s movement to the photoelectric sensors and ensuring that the information collected is efficient and accurate.
Common detection platforms are airborne photoelectric pods and shipboard photovoltaic systems. Usually it consists of the following three parts:
1、Forward-looking infrared cameras, video cameras or laser designators / distance measuring equipment and other photoelectric sensors;
2、Inertial measurement system;
3、Stability control system.
