  • Patent number: 7199738
    Abstract: Dynamic focusing is performed at Nyquist rate FN for the received signal. For each imaging point, a single-bit SDM sample is selected from each active array channel, according to the corresponding focusing delay. A block of data, centered at the selected SDM sample, is defined for each channel. Next, bit-wise block addition is performed to obtain the sum of all the blocks. The block addition output is fed to the demodulation filter. K(=?L/M?) demodulation filters are used. In another approach, the demodulation filters are placed just behind sigma-delta modulators. In each channel, K filters produce successively the demodulated signals for K consecutive imaging points. By taking the sum of samples retrieved from the same memory locations, dynamic focusing is achieved. Since each demodulation filter takes a single-bit SDM sequence as an input data, a simple accumulator calculates the sum of filter coefficients to be multiplied by input samples.

  • Publication number: 20040189499
    Abstract: A multiplierless single-bit dynamic focusing method is presented which can completely eliminate the demodulation error. In the proposed method, dynamic focusing is performed at the Nyquist rate, FN, for the received signal, meaning that the time interval between successive imaging points is the reciprocal of FN. For each imaging point, a single-bit SDM sample is selected from each active array channel, according to the corresponding focusing delay. Then, a block of data, centered at the selected SDM sample, is defined for each channel. Next, bit-wise block addition is performed to obtain the sum of all the blocks. Finally, the output of the block addition is fed to the demodulation filter. In consequence, if the block length is set equal to the demodulation filter length, the proposed method will produce the focused signal without any signal distortion.
