Abstract:
1. A method for suppressing one or more sidelobes of a matched filter output for a pulse compression code, the method comprising: (a) filtering, via a first filter, a matched filter output, wherein the coefficients of the first filter is represented as a first z domain polynomial series by subtracting a second term from a first term, the first term being a first adjustable parameter and the second term being a function of a z domain polynomial series representation of sidelobes of the matched filter output; and (b) filtering, via a second filter, an output of the first filter, the second filter comprising one or more filter stages wherein each of the one or more filter stages is represented by a separate z domain polynomial series as a sum of a third term and a fourth term, the third term being a second adjustable parameter and the fourth term being a function of the z domain polynomial series representation of the side-lobes raised to an integer power of 2.
