<p>Short-range vehicular radar systems are described. In one implementation, an apparatus used in radar applications includes a programmable digital receiver (114) having an adaptable interference filter (216, 218) that is configured to reject radar pulses received from another radar system. In another implementation, a short-range vehicular radar system includes receive and transmission antennae (116(1), 116(2)), a programmable delay generator (201), and programmable receiver (114). The programmable delay generator (201) is configured to control transmission of pulses from the transmission antenna (116(2)) at randomly selected times to prevent ambiguities associated with target objects that are distances away from the transmission antenna (116(2)) that are greater than the speed of light times the pulse repetition rate divided by two. The programmable receiver (114) is calibrated to sample signals received by the receive antenna (116(1)) relative to when the pulses are emitted from the transmission antenna (116(2)).</p> |
