ABSTRACT:
An IF Clutter Canceller using delay lines and acoustic charge transport (ACT) devices to subtract one interpulse period from another interpulse period. The first interpulse period is time demultiplexed with a tapped delay line and stored in ACT devices. The second interpulse period is time demultiplexed through the same delay line as was the first interpulse period. The stored time segments of the first interpulse period are released from the ACT devices and subtracted from the time demultiplexed time segments of the second interpulse period. The resulting clutter cancelled time segments are then assembled into a clutter cancelled interpulse period with a second tapped delay line.
