Research On The Effectiveness Assessment For Electronic/Optical Payloads Collaborative Reconnaissance Of Unmanned Aerial Vehicle

The multi-payload collaborative reconnaissance has become a main operatingmode of Unmanned Reconnaissance Aerial Vehicles (URAV) at present and for thefuture. With the development trend of future air reconnaissance, detection equipmentas the foundation, the paper explored the UAV borne optical sensor application of thecooperative mode of electronic/reconnaissance. The cooperative reconnaissancemodel of the multi-payload is explored; the effectiveness evaluations index system ofthe multi-payload collaborative reconnaissance on unmanned aerial vehicle isresearched and established. Found the evaluation models of reconnaissanceeffectiveness which used Synthesized index model. Then, the feasibility is validatedby the example above the models. Specific studies include:(1) The development of the URAV and the air-borne reconnaissance payload isanalyzed. The working principle, mode and reconnaissance capability of the air-bornereconnaissance payload: electronic reconnaissance device, SAR and tilted CCDcamera is described, and the advantages and disadvantages of three air-bornereconnaissance payload is analyzed. Then, through the comparison of the advantagesand disadvantages of single air-borne reconnaissance payload and multiple UAVscooperative advantages and disadvantages of reconnaissance, validating themulti-payload collaborative reconnaissance has more advantages.Secondly, according to the features of three airborne reconnaissance payloads,the working mode of multi-payload collaborative reconnaissance is analyzed.According to the probability of each reconnaissance payload for target localization,the normal distribution of the confidence interval of multi-payload collaborativereconnaissance when positioning target is obtained. Moreover, through analyzing andresearching the confidence interval, the requirements when positioning target to befulfilled are clearly defined.Finally, the reconnaissance effectiveness of the UAV with payloads wascalculated out. According to analyzing modeling method for the reconnaissanceeffectiveness evaluation, based on the electronic/optical payloads system and Synthesized index model build a system of the efficiency assessment, andparameters to evaluate the reconnaissance effectiveness of electronic/optical payloadsystems in collaborative together is analyzed. Comparison the parameters to evaluatethe reconnaissance effectiveness of "Global Hawk","predator" and the UAV withmulti-payloads, validating the multi-payload collaborative reconnaissance has moreadvantages.
