Abstract. Modern problems of radio-imaging are very closely connected with the development and optimization of high-precision methods of transformation and reconstruction of ultrashort-pulse signals (SIS). The construction of the temporal profile of the echolocation SRS, which constitutes the radio-image of the target or material medium by its radio-physical parameters, and its comparison with the already available in the database radio-portrait responses is the fundamental principle of identification in the super-wide-band active radio vision. This article shows the main stages of modeling the regeneration system, which, together with stroboscopic methods of transformation, allows one to restore an ultra-short radio pulse by one reception in radio vision problems, or by studying the radio-physical characteristics of quasistable media. In previous works, the principles of operation of the radio pulse regeneration system or the regenerative system, advantages and disadvantages, as well as possible realization of high-speed radio components and elements of radio-photonics were considered in sufficient detail. The text formulated the main requirements and analyzed the results of the work together with two different types of stroboscopic transformation systems - with a constant sampling frequency and constant digit capacity. Strobe-frame-sampling technology, due to its understated requirements for the speed of gating pulses, looks more attractive for working with the regenerative system, but the stroboscopic method of scale-time transformation has an indisputable advantage - the ability to reconstruct a fragment of an ultrashort pulse signal with reproducible accuracy not less than the accuracy of restoring the whole momentum. Therefore, it is necessary to investigate the model of signal regeneration in conjunction with the scale-time converter and the gate-frame sampler. The effect of noise, distortion and attenuation on the regeneration of the sequence was investigated and the necessary number of regeneration operations for a certain signal-to-noise ratio was found. It is shown that inherently the regenerative system is an actual addition to the stroboscopic transformation methods, allowing us to restore the reflected pulse from the target for a single reception, ensuring the stealth of the radar in active radio vision systems. Of interest is also the investigation of the radio-physical characteristics of quasistable media capable of changing their properties over a time commensurate with the duration of a single radio pulse. Functioning of the system in combination with stroboscopic transformation methods allows to restore the original radio impulse by one reception at a signal-to-noise ratio of not less than 9 dB with a mutual correlation of not worse than 0.9.

Keywords: ultrashort radio pulse, regeneration, stroboscopic reception, scale-time conversion, strobe-frame-sampling, dynamic characteristics.
