Paper Abstract

A method for in real time shaping of pictures of reflecting objects is described. This method, proposed by author in 1950 (first published in 19821,2), rest upon the usage of pulsed radiation sources and antenna with the beam super-scanning during radiation and reception of pulses3,4. The super-scanning system transforms the time signals into quasi-tomographic periodical spatial structures, because it is possible to receive reflecting signals only from discrete Visibility Layers (Vls) whose position in space is known. With different laws of beam scanning during radiation and reception, this structure has the form of a survey net. Coordinates and dimension of the dynamic objects crossing this net (by the error directly independent of the distance to the object and antenna size) can be measured. It is shown that such system can be adaptive, effects the optimization of energy distribution in the space during observation. Furthermore, a such system permits the necessary information I with minimum energy W, according to criterion (eta) equals I(bit)/W (watt), to receive. This criterion is modification (by author) of thermodynamic Brillouin's criterion of physical experiment efficiency. The model of ultrasound super-scanning tomograph, working in air camera at frequency 115 kHz, (the range of bats and dolphins) was created. The experiments fully confirm the theoretical results. Furthermore, some new effects were discovered. For example, the effect of super-resolution of a group of objects located inside LV through intentionally increasing intervals between signals reflected the remote objects in a group. It is mention also the known hypothesis of the super-scanning mechanism in dolphin's sonar5. In report the principle and some of the super-scanning systems possibilities, are demonstrated. The ultrasonic version of the SSL, working inside ocean or sea, for creation the autonomous high-resolution ground and underwater vehicles or diver's information system, can be used.
