摘要: A correlation method and apparatus for electrical signal transmission ception of coded waveforms are disclosed which makes use a coordinate transformation the original waveform prior to transmission, effecting an inverse upon reception then correlating resultant with waveform. More particularly, its comprises non-linear preferably logarithmic type when utilized in electro-optical processor radar system, example, provides Doppler invariant output data, as well additional noise immunity.
