Title: Yves Doisy: Innovator in Antenna Technology
Introduction
Yves Doisy is a prominent inventor based in Grasse Plascassier, France. He has made significant contributions to the field of antenna technology, holding a total of 7 patents. His work focuses on optimizing power supply methods and enhancing signal processing techniques.
Latest Patents
One of his latest patents is a method for optimizing the power supply for a towed linear transmit antenna for transmitting in omnidirectional mode. This innovative method allows for the achievement of omnidirectional transmission using a towed linear antenna that is longer than the wavelength of the transmitted signal. The antenna features multiple projectors, with spacing between them that is substantially less than half the wavelength. The method involves applying a common transmit signal to each projector, with a delay calculated based on a non-linear term related to the projector's position. This approach enables modulation of the angular aperture of the transmission pattern, facilitating sonar detection systems that can utilize antennas of identical diameters.
Another notable patent is focused on fast coherent processing for codes with periodic line spectra. This invention addresses the computational load associated with conventional signal processing methods that operate through multicopy correlation. By allowing simultaneous correlation of the received signal's spectrum to various copies with different Doppler shifts, the method transforms the received signal through time-frequency analysis. It computes inter-spectral products and performs frequency-time transformations, enhancing the efficiency of signal processing.
