Abstract: A method of radar processing includes selecting a detection threshold in accordance with a mathematical function of angle and/or scaling a radar return signal in accordance with the mathematical function of angle. Apparatus for radar processing includes a threshold selection processor adapted to select a detection threshold in accordance with a mathematical function of angle and/or a scaling value selection value selection processor, which, in combination with a scaling application processor, is adapted to scale a radar return signal in accordance with the mathematical function of angle.

Abstract: In one aspect, the invention is a method, which includes detecting interference in a vehicle system disposed in a vehicle. Detecting includes measuring a frequency of a signal provided from a power source used in the vehicle. Detecting also includes determining if the signal has a frequency within a frequency band used by the vehicle system.

Abstract: A radar system having a transmit signal path and a receive signal path and an event generator which is responsive to command signals provided by a digital signal processor (DSP) is described. The DSP generates command signals and provides the command signals to the event generator. In response to the command signals, the event generator generates event signals in the radar system. The event signals include but are not limited to ramp control signals provided to a controllable signal source which provide RF signals to the transmit path of the radar.

Abstract: A vehicle radar system includes a receive antenna system which concurrently provides signals from multiple receive beams to multiple channels of a multi-channel receiver. The multi-channel receiver concurrently processes the multiple signals provided by the antenna system and provides output signals suitable for further processing. The particular arrangement may also include a transmitter which generates a single or multiple transmit beams. The number of transmit beams may be the same, less than or more than the number of receive beams. This arrangement provides a vehicle radar system which concurrently processes RF signals from multiple antenna beams. By concurrently processing RF signals from multiple antenna beams in an RF receiver, the radar system can derive more accurate information concerning detected objects.

Abstract: A vehicle radar system includes a processing system which operates in one of a plurality of operating modes which are selected based upon an environment (or changes to an environment) surrounding the vehicle radar system. In one exemplary embodiment, the vehicle radar system is provided as a vehicle radar system which operates in one of: a highway traffic mode and a city traffic mode depending upon whether a vehicle in which the vehicle radar system is disposed is traveling along a highway or through a city.
