Method for Detection Performance Simulation under Down Looking AEW Radar
Fang Zhou · Fire Control and Command Control · 2013
The detection range is an important performance index for Airborne Early Warning(AEW) systems.Because the space geometry between the AEW system and target planes is always uncertain and time-varying,the observation data also varies with time,which increases complexity of defining and calculating the effective detection range for the airborne surveillance radar.According to features of the patrolling track and invasion,the maximum detection range equation for surveillance radars is discussed,and the improved clutter spectrum model applied in the AEW environment is also presented.Furthermore the calculation method of the average maximum detection range and the corresponding simulation method of its distribution along the flight path are proposed.Simulation results prove that methods presented here can be adopted to all kinds of AEW radars and achieve better estimation of the effective detection range,which is much valuable for verifying the detection performance of down looking AEW radars.
