Abstract:

It is useful to a sonar instructor to have a device which simulates Doppler shifting of recorded sonar signals. Such a device can consist of a digitizer operating at a fixed rate storing data in RAM. A variable read rate is calculated based on the desired Doppler shifting. Data are read from RAM at a variable rate higher or lower than the fixed rate and converted D to A before being sent to the student sonar operator.
