Abstract : Training simulators for modern analysis sonar and sonobuoy processing equipments demand high accuracy target generators for maximum training value. The essential requirement is for high frequency stability and resolution and a wide range of frequencies, whether these be representing discrete signals or forming modulating envelopes. This requirement is due to the high resolution of such sonars where any instability or steps in the generated signals show on the analysed signal and can confuse trainees. A Passive Acoustic Target module has been developed which satisfies the above requirement. The paper describes the features and the method of realisation of the modules to satisfy the requirement.
