Publication number: 20230170596Abstract: A radar device for limiting radio-frequency power leakage is provided. The radar device includes a first component, and a second component. The first component has a first surface and a first waveguide that defines a first cavity. The second component has a second surface and a second waveguide that defines a second cavity. A first groove is provided that acts as a choke, and the first groove is defined in the first surface. The first component and the second component are assembled so that an air gap is maintained between the first waveguide and the second waveguide. The first waveguide and the second waveguide are configured to facilitate transmission of radio-frequency power. The first groove is configured to reduce leakage of radio-frequency power through the air gap. Additional chokes may also be included.Type: ApplicationFiled: November 30, 2021Publication date: June 1, 2023Inventors: Ricardo Andres Perez Benitez, Michael Cann, Lindsay Lilburn, Cameron Malcolm Arthur

Patent number: 10215842Abstract: Various implementations described herein are directed to frequency correction for pulse compression radar. In one implementation, a method may include generating a first transmission signal using a pulse compression radar system based on an ideal waveform signal. The method may also include measuring a frequency of the first transmission signal at an output of a transmitter module. The method may further include comparing the measured frequency of the first transmission signal and a frequency of the ideal waveform signal. The method may additionally include generating pre-distortion coefficients based on the comparison, where the pre-distortion coefficients are configured to compensate for a difference between the measured frequency of the first transmission signal and the frequency of the ideal waveform signal. In addition, the method may include generating a compensated transmission signal using the pulse compression radar system based on the pre-distortion coefficients and the ideal waveform signal.Type: GrantFiled: January 22, 2016Date of Patent: February 26, 2019Assignee: Navico Holding ASInventors: Roger Phillips, Graeme Bell, Gregor Storz, Lindsay Lilburn
