ANTENNA STRUCTURE FOR REDUCING BEAM SQUINT AND SIDELOBES

摘要

An example radar system includes a transmission array and a reception array, each aligned as a linear array. The radar system also includes a transmitter configured to cause transmission of radar signals having a center frequency by the transmission array. The radar system also includes a receiver configured to receive radar signals having the center frequency that are received by the reception array. The radar system also includes a processor configured to process received radar signals from the receiver, and adjust the center frequency from a first center frequency to a second center frequency. The adjusting of the center frequency from the first center frequency to the second center frequency causes the frequency -dependent transmission radiation pattern of the transmission array to tilt in a first direction and the frequency -dependent reception radiation pattern of the reception array to tilt in an opposite direction from the first direction.
