Abstract

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.
