Title: Innovations of John J Gallagher
Introduction
John J Gallagher is a notable inventor based in Turnersville, NJ (US). He holds an impressive portfolio of 14 patents, showcasing his contributions to the field of radar technology. His work has significantly advanced the capabilities of radar systems, particularly in the areas of pulse compression and Doppler filtering.
Latest Patents
Gallagher's latest patents include a complementary-sequence pulse radar with matched filtering and Doppler. This innovative radar transmits dispersed pulses, where the subpulses are modulated by mutually complementary code sequences. The design ensures that the main range lobes add while the range sidelobes cancel. The received pulses are processed through multiple channels, each equipped with a mixer-oscillator combination to remove specific Doppler phase shifts. The signals are matched-filtered to produce time-compressed pulses, effectively suppressing undesirable range sidelobes. Another significant patent is a radar system with pulse compression and range sidelobe suppression. This system digitizes echo signals from targets and applies them over various signal paths, utilizing differential exponential signals for conversion to baseband. The signals undergo processing through a pulse compressor and range sidelobe suppressor, ultimately achieving full suppression of range sidelobes.
