| Abstract: | Focused on the scattered signal of the freque ncy modulated continuous wave (FMCW) automotive collision avoidance radar, a system filter is designed to get the useful part of the scattered signal from the radar. The principles and implementation of the fore wideband analog band-pass filter are shown here, the adaptive programmable filter which is controlled by Digital Signal Processors (D SP) is also introduced in detail. The experiment result proves that the system f ilter can effectively decrease the influences of both disturbances and noises, a nd can successfully keep the useful signal in the meanwhile. |
