The invention designs an optimized radar target search algorithm, the algorithm satisfies good detection performance, and the radio frequency stealth performance of the airborne opportunity array radar is improved.

Description

technical field [0001] The invention relates to an airborne opportunistic array radar resource optimization technology, in particular to a target search resource optimization method based on a hybrid phased array-MIMO radar. Background technique [0002] With the emergence of new combat concepts, the combat space of modern warfare has extended to land, sea, air, and sky. The ever-changing combat environment is full of unknown challenges. The ability to perceive information in combat plays an important role in the outcome of the war. The radar system can detect and identify various targets by means of radio positioning, and is an important information perception system in combat. However, with the continuous upgrading and development of various combat system technologies, such as unmanned combat aircraft, warship combat systems and anti-radiation missiles, the survivability of current radar systems has been greatly threatened. As the most widely used radar system, phased arr...

Problems solved by technology

[0005] Although the above described method satisfies a good detection probability and the radar’s search and detection capability has also been improved to a certain extent, due to the complex and changeable radar combat scenarios, there are many false targets and interference radiation sources, which make the threat level of the target very high. Difficult to determine

Therefore, the application of existing methods in complex combat scenarios has certain limitations, and the radio frequency stealth performance is not high
