Title: Ralph H. Halladay: Innovator in Radar Technology
Introduction
Ralph H. Halladay is a distinguished inventor based in Huntsville, Alabama, known for his significant contributions to radar technology. With a total of nine patents to his name, Halladay has developed innovative solutions that enhance the functionality and efficiency of radar systems.
Latest Patents
One of Halladay's latest patents is the "System and method for radar calibration using antenna leakage." This invention provides a simplified means of calibrating radar channels in amplitude and phase by utilizing natural signal leakage between antennas. The system employs a wideband sinusoidal Frequency Modulated Continuous Wave (FMCW) waveform as a calibration signal, which is radiated from the transmitting antenna and enters the radar receiver through natural leakage. This technique offers a low-complexity solution for rapid wideband calibration, serving as a practical alternative to conventional methods.
Another notable patent is the "Multiple-Antenna Jamming System" (MAJS), designed for missile-borne jamming of active protection system radars. The MAJS utilizes multiple antennas to minimize shadowing effects and channelizes jamming signals into in-seeker-band and out-of-seeker-band signals. This synchronization with the missile seeker’s emissions ensures effective jamming while preventing the RF seeker from becoming desensitized to jammer energy.
