In problems of a detection there are low -contrast objects on the images used algorithms usually, use the correlation and planimetric approaches. They are implemented by methods of a compounded filtration and differential methods [1,2]. In operation the new approach to a detection low -contrast of objects on the synthesized and radar-tracking images spreading covers grounded on fiactal exposition of a phon or terrain is offered [3]. In practice h c t a l dimensionality D measure indirectly -on a declination of dependence S=S (6 ), where S -measured value, for example, length of a line or area of a figure etc., 6 -step of measuring or size of a scanning window. It's shown, that for the first time designed algorithm of a detection of object using fractal indications, stabilly operates at low values a signal / phon (-30dB and below). The algorithm at the low requirements to inventory ensures high efficiency of measurings in a mode of actual time.In the report the problems of hardware embodying of digital radars surveyed on the basis of the non conventional concept of their build-up with a fractal information handling on a carrier frequency in at microwaves with an opportunity of deriving of unique basis of a composite sounding signal.Characteristics of a bifrequency numeral radar the following: -wave length -8, 6 and 20 mm; pulsing power -10-500 mW; basis of a signal >lo6; a range resolution <2 m; an operating range <5 and 4 0 0 km; power consumption <150 W.In the report algorithms of operation and methods of a substantiation of the basic parameters and estimation of efficiency of altemate variants of millimeter radars of a detection ground of objects also presented. The algorithm. of operation of radars of a detection of ground objects is submitted and the estimation of their efficiency is carried out [4]. In a result the following deductions are made.1. The obtained performances of radars (operating range, resolving ability on range and angular coordinates, and also on sector of the radar-tracking review) are in limits of the requirements. The level of technique of microwaves allows to create such systems already now.2. The estimation of efficiency of alternate variants of systems of a detection not enough of contrast of objects has shown, that efficiency of radars on frequency be higher 100 GHz up to 20 % above can, than on frequencies is lower 30 GHz.

Abstract. Modern development level of generation methods of powerfull electromagnetic impulses and radiation forming ways defines development possibility of wide class of directed energy systems and means. In electromagnetic systems and means impacted on biological objects (human) and environment development area and for force systems in electronic warfare (EW) area the following in most known: electromagnetic means of lethal effect, large power generation means for force systems of EW, electronic means of non-lethal effect and means of directed electromagnetic effect on environment. In the first part of the paper questions of powerful electromagnetic impulses generation improvement for force systems creation of radio-electronic suppression of different kinds of radio-electronic systems (RES) and especially systems of modern high-precision weapon are highlighted. It is exceedingly important problem in perspective armament and military equipment development. Methods and ways of powerfull nanosecond impulses generation are discussed. It contains the following works: -theoretic justification of powerful nanosecond impulses generation method abilities and they's main parameters for possible practical use in perspective systems of force electronic warfare of RES termination development is made; -results of foreign and domestic researches of creation of nano-and microsecond duration UHF-pulses and ultra-thin electromagnetic pulses and also electromagnetic radiators with magnetoimplosive current generators supply are given -the variants of UHF weapon used abroad are presented and also examples are given for creation of means of directed electromagnetic impact to human for the fight against terrorism. In the second part of the paper basing on interactive materials, issues of geophysical perturbations in ionosphere made naturally and artificially are highlighted as powerfull impact sources in nature. Corresponding description of deliberate methods and means of impact to environment (HAARP type of RLS) and directing of radiation heating stands and secondary ionosphere radiation radiomonitoring is given. In the final third part of the paper problems of possible (expected) development directions of electromagnetic radiation impact on physical objects and environment methods and they's ways of solving are approximately formulated.
