Experimental samples of stroboscopic transducers for pulsed geo-radar were created and features of active and passive regimes of slot multi wide band pulse generator were defined. The generator uses the dispersion compression of the working electromagnetic pulse. A model of the electromagnetic field backscattering by the sea surface and comparative analysis of methods for supporting small low-altitude targets was developed. A study of diffraction gratings was done, the basic requirements for spark and arc sparks was formulated. The principles of their construction were analyzed and the mathematical model of the autodyne generator with varaktorny lane is developed. Frequency structure and modeling of the autodyne response signal spectrum for the passive radio vision system model calculations of the main beam characteristics for various variants of using a focused diffraction antenna, research of clinotrons operation, for vacuum installation URM3.279.014 new equipment and methods were developed.
