Techniques are disclosed for detection and ranging systems and methods to improve range resolution, target separation, and reliability. A method includes selectively attenuating a signal representing a ranging system return or echo from targets so as to suppress side lobes or other undesirable artifacts appearing in the signal due to noise, interference, and/or distortion. A method may additionally or alternatively include rejecting interference events in ranging system returns by comparing a received return with that expected from a target illuminated by the ranging system, as determined by characteristics of its particular ranging sensor, and rejecting or attenuating returns or portions of returns that fail to match those characteristics in time or space. A system configured to perform such methods and comprising a transducer/antenna, a transceiver, a controller, and/or other logic devices implementing a pulse generator, correlator, selective attenuator, comparator, buffer, subtractor, and/or output circuit is also disclosed.
