METHOD FOR DETERMINING THE BREACH air borders of protected sites AND DEVICE FOR ITS IMPLEMENTATION

摘要

1. A method for detecting malfunction of the air boundary of the protected object, comprising irradiating the offending electromagnetic energy, characterized in that the taking of the reflected intruder signals with continuous frequency modulation for a unilateral linearly increasing sawtooth law (NLCHM signal), at least four receive antennas PRA1, PRA2, PRA3 PRA4 and established in the world, on the circumference, equidistant circumferentially from each other, with base lengths L between the opposite PRA1 and PRA2 and m akzhe PRA3 and PRA4 and emit NLCHM signal in the direction approaching to the object offender through a transmit antenna (SDA) mounted in the center of the installation circumferential gear, and reflected by the intruder and emitted NLCHM signals are multiplied in the four mixers (CM1, CM2, CM3 and CM4) the first inputs connected respectively to the outputs PRA1, PRA2, PRA3, PRA4 and second inputs connected to the low transmitter output NLCHM signal combined with a PDA, to produce and detect four signals with specific difference frequency: Fp ÷ Fp = [( Di + Dj) Fm × df m / C] - (2 × Vi × f / C) = Fp, where Di, Dj - current distance from the intruder to, respectively, gear and SDA, C, Vi - respectively, the speed of light and the intruder, f, Fm, dfm - frequency, modulation frequency and frequency deviation NLCHM signal, then, in sequence starting instants of the detection signals with frequencies Fpi Fp, and Fpi Fpi values ​​tp time intervals t, respectively, between the signal detection moments with frequencies Fpi Fp, and Fpi Fp determine cell memory (YAPZU1 ÷ YAPZU4) that store precalculated data values: ds
