Abstract :
The problem of detecting a signal that has both magnitude and sign is considered. A new type of correlation device, which employs the derivative of the correlation function, is proposed for measuring target range and position, and an analysis to determine the most useful waveform is made. The effects of white noise accompanying the input signal are minimized when an input waveform of long duration, wide bandwidth, and high derivative power is chosen.
