摘要： There is described a digital sonar receiver having a novel beamformer, own doppler nullifier (O.D.N.), and adaptive time varied gain controller. The beamformer interrogates a multi-element transducer by utilizing an interleaved sampling scheme which samples the elements in the transducers array sequentially, in such a fashion that continuous, uniformly spaced samples are obtained. The samples are subsequently converted into digital format, weighed and summed. The O.D.N. eliminates the own ship's doppler effect on the beam output signal resulting in a half beam output signal representative of the target doppler. The O.D.N. offsets the frequency of the beam output signal and a digital generated signal representative of the own ship's doppler. The O.D.N. multiplies these two offsetted signals resulting in a signal lying in each of the sum and difference frequency bands for which the signal lying in the difference frequency band corresponds to the target doppler. The adaptive time varied gain controller varies the gain of preamplifiers at the input of the sonar receiver to be inversely proportional to the momentary average reverberation level of the medium in which the receiver operates. The adaptive time varied gain control apparatus initially sets the gain of the preamplifiers to be inversely proportional to a standard reverberation curve during the first ping-cycle and subsequently updates the gain of the preamplifiers during each successive ping-cycle by computing a gain correction from the average value of a predetermined number of beam output signals.

摘要： An underwater detection and identification method and apparatus utilizing the principle of parametric cross-modulation of ultrasonic frequencies within a non-linear propagation medium for obtaining an acoustical signature of an object under observation. The object is illuminated by ultrasound of suitable, high frequency projected from the observation platform and echo signals are received composed of side bands generated by combining the illuminating frequency with the relatively low signature frequency. The received ultrasonic side band frequency signals are then processed electronically to yield a signal representative of a characteristic of the object. The apparatus is essentially a hybrid, active-passive sonar operating in a continuous uninterrupted mode.
