During the lead researches directed on perfection antennas of systems of stationary both mobile complexes of the radiocontrol and a special software used in them, the following basic results are received. 1. On the basis of the lead analysis of achievements in the field of creation radio direction finding antennas systems and devices, and also - methods and algorithms of real - time processing of signals accepted by them, the most significant available problems are revealed, the primary goals of researches are put and perspective ways of their decision are planned. 2. With use of methods of mathematical modelling, computing electrodynamics and techniques of natural experimental researches, methods of approximation of spatial distribution of a field near to the case of the carrier of direction finding antenna array of the dipole type, not demanding uses of the information on geometry and material properties of scatterers, and allowing, in (2-4) time are developed and investigated, to raise accuracy of direction finding and resolution of complexes of the radiocontrol of mobile basing. 3. Techniques of designing direction finding antennas, allowing are offered and investigated: to reduce number subgratings, used for functioning in a range of frequencies with factor of overlapping 150 and more, with (2-3)-х up to one, and, thus, considerably to reduce overall dimensions and weight the antenna system; to raise sensitivity of the equipment of the radiocontrol in short-wave and ultra-short wave bands on (5-10) dB due to development of a technique of designing by the antenna system, allowing to use the currents proceeding on a lateral surface of the carrier, for essential increase in the working length antennas elements; the technique of designing direction finding antenna system consisting of directed superbroadband elements, a "dead" zone described by absence in antiaircraft area is developed. 4. The method of real - time processing of the accepted signals, based on use of a database of the basic signals corresponding to reaction by the antenna system on falling of electromagnetic waves with vertical and horizontal polarization from lines of azimuthal directions is offered, allowing not only to estimate angular coordinates of a source of a radio emission with accuracy (1-2)0, but also to measure the parameters de-scribing a kind of polarization of falling electromagnetic waves. 5. The technique of designing direction finding antennas arrays of ultra-short wave bands and the MICROWAVE bands distinguished in small overall dimensions and described factor of amplification of elements in structure of a array (5-13) dB is developed. 6. The technique of designing multiband antennas arrays formed enclosed each other symmetric or asymmetrical TEM- horns, functioning in the decimeter, centimetric and millimetric wave bands possessing in the sizes, not exceeding the sizes is developed by the similar antennas system of a decimeter range. Variants of designs of antennas arrays which elements are characterized by average entrance resistance 100 Ohm and 50 Ohm are developed. Presence internal antennas elements is shown, that, and also - antennas arrays insignificantly changes entrance characteristics and the directed properties of an external radiator in a superwide band of working frequencies. 7. The technique essential (more, than in 2 times) increases of resolution and accuracy of an estimation of angular coordinates of sources of a radio emission with the help of algorithms of the supersanction several radio sources, carried out is offered and approved due to the account of distortions of an observable field the antennas system and the case of its carrier. 8. The technique of minimization of distortions of the form and duration of the supershort videopulses brought multi-dipole antenna, based on synthesis of strip devices of the phase correction containing concentrated jet elements is developed. The technique enables to realize antenna systems of the monopulse radiodirection finders intended for an estimation of angular coordinates of sources of a radio emission, forming super-short duration videopulses. 9. Experimental researches of complexes of the radiocontrol equipped developed antennas systems and the special software in which algo-rithms of real - time processing of accepted signals are realized are lead. It is shown, that their use allows: to reduce number of letters the antennas system; it is essential to raise sensitivity of complexes the MICROWAVE band (up to 3-8 dB); it is essential to increase accuracy direction finding (up to 2-4 time).
