RADAR RECEIVER WITH LARGE DYNAMIC RANGE BY INTERMODULATION OF THIRD ORDER

摘要

FIELD: a radar receiver with a large dynamic range by intermodulation of the third order refers to the field of radiolocation and may be used in radar stations in quality of a radar receiver.;SUBSTANCE: a radar receiver with a large dynamic range by intermodulation of the third order has an amplifier of high frequency, a high frequency filter, a second amplifier of high frequency and a second high frequency filter, an attenuator, a mixer, a diplexer filter, a preliminary low-noise amplifier of an intermediate frequency, a filter of an intermediate frequency on surface acoustic waves, a second low-noise amplifier of an intermediate frequency. A phase detector, an analogous-digital amplifier connected one after another and a filter of an oscillator's signal switched between the output of an amplifier of an oscillator's voltage and the second of the input of the mixer besides the mixer is fulfilled as a mixer of high level.;EFFECT: expansion of the dynamic range of the receiving track by intermodulation of the third order.;4 dwg
