  • Adaptive pulse shaping implementation and method for control of solid state transmitter spectrum and time sidelobes
    Patent number: 5731784
    Abstract: A radar detection system includes a transmitter and a receiver. The transmitter generates a pulse including a first subpulse generated at a first predetermined frequency and a second subpulse generated at a second predetermined frequency. At least one of the first and second subpulses include a digitally adjusted rise time and fall time, each of the rise time and fall time being separately adjustable independent of the other to provide for the relative lowering of transmission power above and below the first and second predetermined frequencies. The transmitter then transmits generated first and second subpulses at the respective first and second predetermined frequencies, as digitally adjusted in rise and fall time.
