Abstract: Airspace covering blind area and Doppler blind zone occur as single airborne early warning (AEW) radar is operated to probe targets. The parameterized mathematical model of AEW radar patrol routes was established. The calculation formula of AEW radar target detection probability was derived. And the patrol routes optimizing criterion of single AEW radar was proposed based on the 2-norm of accumulated detection probability matrix. The mission routes programming problem of multi-AEW radar cooperation probing was studied further and the optimizing criteria was presented in that multi -AEW radar cooperation can help reduce the bad influence of airspace covering blind area and Doppler blind zone on detection performance. Finally, the effects of time interval and distance separation between AEW radars on accumulated detection probability of the key surveillance area were analyzed. Simulation results show that the optimizing criteria founding on 2 -norm of accumulated detection probability matrix are effective which are conducive to maximize the coverage and target detection probability of AEW radar.
