摘要： Systems and methods for sensing the surroundings of vehicles via vehicle mounted radar sensors. A directional transmitter array transmits radiation into the region surrounding the vehicle and a receiver array receives the radiation reflected back. Controllers may use self-velocity calculation modules, wall detection modules, dynamic range enhancement modules, double reflection detection modules and the like to harvest useful information such as the vehicles relative speed and the identification of hazards in its surroundings.

摘要： A printed circuit board mounted radar system for monitoring a target region, including an array of transmitting antennas mounted to a printed circuit board, an array of receiving antennas mounted to the printed circuit board, a wave deflection mechanism mounted to the printed circuit board configured such that waves transmitted perpendicularly to the board by the array of transmitting antennas are incident upon the wave deflection mechanism and are directed radially away from the board, and waves reflected from objects within the target region radially towards the wave deflection mechanism are directed towards the receiving antennas in a direction perpendicular to the board.

摘要： Systems and methods for providing wide field-of-view radar arrays. Quadrature phase-shift keying (QPSK) beam forming reduces side lobes by applying a phase shift to transmitted signals to selected transmitting antennas. Super-hemispherical radar coverage at high gain in both broadside and end-fire directions is provided by beam directing elements mounted to a printed circuit board.

摘要： Antenna array systems and methods for simulating QPSK beam forming having binary phase shifter associated with each transmitting antenna configured to apply a phase shift of 180 degrees to a transmitted signal, and a controller configured to send instructions to the binary phase shifters. The receiving antennas are connected to a post processor comprising a memory operable to save received signals; and a processing unit operable to apply a 90 degree phase shift to selected received signals stored in the memory, and further operable to sum received signals stored in the memory. Optimized antenna array configurations are disclosed.
