ABSTRACT:
Three term ripple suppression apparatus for suppressing ripple in a radar image derived from received radar signals. The ripple suppression apparatus comprises a field programable gate array having a radar signal input, a clock signal input, a code select signal input, and a radar signal output. The field programable gate array is adapted to implement a transfer function having the form ##EQU1## where z is a unit delay operator, and where B and C are coefficients that are set based on the code length N. First and second multipliers are respectively coupled to the field programable gate array that are adapted to receive first (B) and second (C) coefficients and transfer them to the field programable gate array for use in processing the radar signals using the transfer function. Code lengths of 1, 3, 7, and 13 are supported by the currently implemented three term ripple suppression apparatus. The present invention is compact, reliable, reprogrammable, draws relatively little power, and is relatively inexpensive to develop.
