Abstract
A radar apparatus is provided having an antenna that has a frequency-dependent directional characteristic. The radar apparatus includes a transmitter circuit designed to generate a first frequency-modulated continuous wave (FMCW) frequency ramp having a first center frequency and at least one second FMCW frequency ramp having a second center frequency, which is different than the first center frequency. The transmitter circuit is configured to drive the antenna using the first FMCW frequency ramp to produce a first directional characteristic for the at least one antenna, and to drive the antenna using the at least one second FMCW frequency ramp to produce a second directional characteristic for the antenna, where the second directional characteristic is different from the first directional characteristic. It is thus possible to exploit an antenna squinting effect in order to increase an angular resolution.
