Radar sensitivity and resolution in presence of range sidelobe reducing networks designed using linear programming

Binary phase-coded waveforms are widely used in modern radar systems. In linear receivers the sidelobes present at the output of the compression filter cause a reduction of the useful dynamic range. Many procedures have been developed to reduce the sidelobes based on a compensation of their Fourier spectra or on a design of an optimum single mismatched filter. The present paper uses linear programming technique to define an optimum sidelobe reducing network which introduces small mismatching losses when cascaded to a matched filter. The influence of quantization in a digital implementation is evaluated.
