FIELD: radio engineering, possibly development of actuating radio-electronic devices for controlling explosion. ^ SUBSTANCE: non-linear radar includes reference generator, power amplifier, low frequency filter, receiving and transmitting antennae, first band filter, receiver and display. Novelty is that radar also includes frequency divider, linear frequency-modulated generator, mixer, second band filter, limiting amplifier and third band filter. Invention provides lowered possibility of operation of actuating radio-electronic devices at finding them until 0.1 due to reduced spectral density of power of irradiating signal in the result of modulating its carrier frequency according to linear law. ^ EFFECT: enhanced safety at carrying out operations for removing mines. ^ 3 dwg |
