Paper Abstract

Results of theoretical and experimental research to develop a locator with antennas performing beam scanning during both the emission and reception of pulses are presented. The reflected signals are received within discrete `visibility' layers formed due to beam scanning during reception. The locator is shown to have a number of advantages in comparison with the conventional locator. The known distribution of visibility layers in space allows one: to create adaptive systems ensuring reception of the required information with the minimum energy expenses; to attain `superresolution' of objects (at distances smaller, than required by the Rayleigh criterion); to improve noise immunity of the locator. It is demonstrated that a `quasi- holographic' data-processing system can be developed, similar to the synthesized antennas aperture system proposed in the 50s by Emmett Leath. An ultrasonic version of the `superscanning' locator is described. The experimental results totally confirm the theoretical predictions.
