The problems of small base ultrawideband radar

Simulation results have shown a perspective of application of approach for the radar object (RO) form evaluation with use of genetic functions when aperture synthesis realizes a small angle base of surveillance. The accuracy of the object form evaluations increases with the decrease of sounding pulse duration and increase of the distance between the receivers. Application of a suggested scheme of coordinate determination for this aim allowed us to obtain the object form evaluations when the receiving system base is 10 m. Influence of measuring noise on the accuracy of approximation and determining of coordinates makes it necessary to increase the signal/noise ratio, e.g. owing to the increase of the radiated signal power. Besides, the accuracy of the RO form evaluation will increase and processing velocity will decrease when adding new genetic functions. A search of optimum composition of genetic functions is a significant task
