Design and Construction of Extracting Circuit

The principle of radar echo analysis for extracting the Doppler signal of moving echoes (eliminating fixed echoes) is based on the use of a sampler associated with a hold capacitor followed by a band-pass filter.The filter cut-off frequencies are chosen as a function of the types of targets to be d...

description The principle of radar echo analysis for extracting the Doppler signal of moving echoes (eliminating fixed echoes) is based on the use of a sampler associated with a hold capacitor followed by a band-pass filter.The filter cut-off frequencies are chosen as a function of the types of targets to be detected. The fast filter has a pass-band from 190 Hz to 1800 Hz. These frequencies correspond to Fast targets having radial velocities of between approximately 10 Kph and 200 Kph.The slow filter has a pass-band from 60 Hz to 230 Hz. these frequencies corresponding to slower targets. Whose radial velocities lay between approximately 3.5 Kph and 13 Kph.
