Description

A simple magnetoacoustic storage correlator (MASC) was tested as a pulse compressor in an ultrasonic nondestructive testing application. The pulse compression ratio reached was 30. Higher compression ratios are readily available through choice of different device lengths and device operating regime. The system is flexible; 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. 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.
