ABSTRACT:
A method of testing an acoustic array antenna, consisting in using at least one independent acoustic transducer of non-directional type for receiving the same signal simultaneously via the transducer and via the antenna, and in comparing the received signals to identify possible fixed echoes and to verify whether or not the antenna and its associated cabling, relay, amplification, and signal generating and processing means are in a nominal operating state.
