Low-logistics echo repeater, transponder, and monitor for acoustic tests and evaluation. ERAS is a commercial-off-the-shelf instrument used to echo repeat, transpond, monitor and produce complex calibrated transmissions. This compact instrument is used to simulate different noise signatures including sonar pings, ship noise, movement, and Doppler effects. It is ideally suited for test and evaluation exercises, as well as to calibrate passive and active sonars for range and detection, and to evaluate novel concepts of operations.Key features:
Transmits custom calibrated signals over a wide frequency range.
Replies at a calibrated source level and range.
Monitors incoming signals, records and repeats them. The echo repeat mode is triggered in response to an acoustic signal or an operator request.
It is compact and can be mobilised from a small RHIB.
ERAS operates across a broad range of Low to High Frequencies. Using the following two bands:
Band 1 Low Frequency (LF) – 3 kHz to 23 kHz
Band 2 High Frequency (HF) – 23 kHz to 50 kHz
In addition, ERAS can transmit at up to 171 dB re 1 µPa@1m with a flat transmit response to within ±1.5 dB across these two frequencies bands. The LF source level can be increased to 180 dB re 1µPa@1m between 7 kHz and 19 kHz.
