Aircrafts such as helicopters, fighter planes, transport planes, and special military aircraft may be attacked by missiles or rockets fired by armed personnel during a conflict. Airborne Electro-Optical (EO) warning system can warn the incoming missiles or rockets, so that the airborne aircraft can take countermeasures and improve the survivability of the airborne aircraft. This paper introduces methods of testing the main function and performance of the airborne EO warning system, which can effectively and objectively evaluate the performance of the system and effectively improve the bidding efficiency.
Hypersonic target in near space put forward new challenge to the early warning system. The airborne IR early warning system is an important part of air-based infrared detection system to hypersonic vehicle, which will play a part in the preparedness of space echelons of missiles warning systems. The infrared radiation strength of near space hypersonic vehicle is discussed. It utilized MODTRAN software to simulate the atmospheric transmission rate under different conditions. The Hudsons classic distance formula is used to calculated the caliber. It discussed the feasibility on infrared detection system to hypersonic vehicle. It designed an onboard infrared detection system to hypersonic vehicle which can function well on the target 900 km away.
