Latest Patents

Koppelman holds a patent for an underwater viewing system. This system substantially reduces the number of hydrophones in the receiving array and associated circuitry. It achieves this by utilizing a plurality of transmitting transducers that are spaced apart by a known distance. Each transducer emits a coded output, typically at a separate frequency. The receiving array, which is preferably square or rectangular, includes a substantial number of receiving hydrophones. A synthetic aperture technique is applied, where the reflected signal arriving at each hydrophone is amplified, modulated with a lower frequency reference signal, filtered, digitized, and stored in memory. The computer compares each digitized hydrophone signal against sine and cosine reference signals at each frequency and performs a Fourier analysis to reconstruct a primary image. This innovative method allows for the synthesis of an image with an effective number of image points that exceeds the actual number of hydrophones.
