  • Method and system for enhancing data rates
    Patent number: 8928524
    Abstract: The present disclosure relates to the field of pulse compression in signal processing, and more particularly, to systems and methods for the synthesis of waveforms for suppressing sidelobes and sidebands using a combination of time and spectral control. More specifically, the present disclosure relates to a set of waveform symbols which can be used to maximize use of disaggregated grey-space spectrum, adapt to changing spectral condition, and maintain or enhance data rates relative to standard binary phase-shift keying (BPSK) under normal conditions.

  • Systems and methods for suppressing radar sidelobes using time and spectral control
    Patent number: 8436766
    Abstract: Methods and systems are disclosed for radar pulse compression signal processing. Methods include generating a function that quantifies radar signal characteristics and using a processor to calculate time-domain derivatives of the function in the frequency domain. Methods also include generating a function that quantifies radar signal characteristics as a sum of sidelobe levels; and using a processor to control the sidelobe levels by obtaining gradients of the function in the spectral domain.
