Radar apparatus with determination of presence of target reflections

摘要: A low-cost compact radar apparatus measures a distance to target and the relative speed of target. The has transmitter for transmitting pulse signal receiver receiving reflected from received is converted into binary signal, which sampled by sampler accumulated in cumulative storage unit. Addresses unit correspond an interval between transmission reception signal. According interval, are calculated at high speed. carries out many accumulation operations, improve S/N ratio speedily detect even weak
