Abstract

The article deals with optimization and synthesis of multifunctional unmanned aerial vehicles (UAV) with account for the noises impact. The purpose of the work consists in of multifunctional UAV functioning optimization intended for sequential implementation the tasks of load delivery and making a terrain reconnaissance by remote probing technique. The necessity for this task fulfillment in military art is explosives delivery and release, as well as explosion aftermath assessing.

The authors employed the well-known results of the UAV navigation provision task using local radio-technical navigation system, allowing achieve high accuracy in the UAV delivery to the specified target no less than the satellite radio-navigation systems accuracy. The article considered the cases absence of radio-navigation signal suppressing, as well as multichannel Doppler signal processing and pulse-to-pulse phase manipulation of navigation signal under conditions of radio-electronic counteraction.

The task of the multifunctioning UAV functioning optimization, performing functions of the load delivery to the specified point (a) and (b) making reconnaissance in the vicinity of this point under conditions of local radio-navigation system (pseudo- satellites) application was formed and solved.

As the result of the UAV functioning optimization at the relatively small distances, the optimal functional dependence of the UAV positioning at the specified point probability on the flight distance was obtained.

The results obtained in the article can be implemented while developing and operating the multifunctional UAV of the similar purpose. The authors formulated and solved the problem of the multifunctional UAV functioning optimization, sequentially performing the functions of (a) load delivery to the specified point, and (b) making reconnaissance in the vicinity of this point

The results of the multifunctional UAV operating mode optimization at relatively small distances demonstrated the presence of the optimal functional dependence of the probability of the UAV positioning at the specified point ono the UAV flight distance value.
