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