Applied Physics and Mathematics Annotation << Back TECHNOLOGY AND COMPLEX OF SCALE PHYSICAL HYDROACOUSTIC SIMULATION OF RADAR WITH SYNTHETIC APERTURE AND THE PROBING SIGNALS SUCH AS DIGITAL FREQUENCY SEQUENCES V.N. TROFIMOV The article describes the technology and complex of scale physical hydroacoustic (SPH) simulation of radar with synthetic aperture and radar signals such as digital frequency sequences. Considered simulation technology includes a recording of ultrasonic echo signals refl ected from scale models of radar targets in a hydroacoustic tank, and then use of the recorded signals for mathematical or hardware-in-the-loop simulation of radar. A technique modeling of radar by use of echo signals received by the SHP simulation for any displacement of an object relative to radar, is described. Radar images of extended objects, obtained by use of mutual mathematical and SPH modeling in wave scale 1: 100 for 3-centimeter wavelength range, are presented. Digital radar signal simulator for hardware-in-the-loop simulation, based on echo signals obtained by the SHP simulation, is described. Keywords: synthetic aperture radar, scale physical modeling of radar, mathematical modeling of radar, radar images, ultrasonic echo signals, a digital simulator of radar signals.
