Development of digital part of ratio-type radiometer

It is continuing to study the new type of chopper radiometer, providing unbiased estimation of power (or its associated features) of radiometric signals at the receiver with instability predetection section. The receiver block diagram is developing. Its analog and digital part are concretized. The basic operations of the signal processing in digital part implements in FPGA, which is digitized after preliminary analog processing (transfer to the intermediate-frequency, amplifier and envelope detector of the noise radio-signal modulated square wave).
