Abstract
A simple magnetoacoustic storage correlator was utilized as a pulse compressor in an ultrasonic nondestructive testing application. The pulse compression ratio reached was 30, which the theoretical maximum obtainable with our experimental parameters. Much higher compression ratios are readily available through choice of different device lengths. The system offers good flexibility; it is not limited to any particular type of large time-bandwidth signal. The correlator reference signal is easily programmable and erasable, and can be changed at any time. Unlike digital pulse compressors, this system offers real time correlation signal processing at a repetition rate that is only limited by the temporal length of the large time-bandwidth signal.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
