Abstract

A frequency steered sonar (1) includes a transducer (10) configured to transmit underwater an ultrasonic transmission wave comprising a plurality of frequencies (fl-fm), each frequency of the plurality of frequencies being associated with a transmission direction, to receive a reflection wave from the transmission wave reflected on an underwater object, and to generate a reception signal from the reflection wave; and a filter (11a) configured to filter the reception signal in each transmission direction, a first time range (ΔT1) of the filtered reception signal being outputted from the filter by attenuating signal components having a frequency outside of a first bandwidth (Δf4), and a second time range (ΔT2) of the filtered reception signal being outputted from the filter by attenuating signal components having a frequency outside of a second bandwidth (Δf3), and to output the filtered reception signal for display or storage.
