1. A method for obtaining an indication of range from a first object to a second object, the method comprising:

  • transmitting a signal from the first object;

    receiving the signal reflected from the second object;

    digitizing the received signal into a plurality of samples;

    buffering the samples;

    repeatedly convolving each one of at least a portion of the buffered samples R times, wherein R>

    1; and

    detecting a time of the received signal'"'"'s center of energy from the convolution results, so that the time of the received signal'"'"'s center of energy is an indication of the range from the first object to the second object.
