Abstract: A method for a radar system having a plurality of antennas is provided. The method includes processing a plurality of radar signals for determining a distance between the radar system and at least one target and a velocity of the at least one target, thereby forming a plurality of processed radar signals. Each radar signal of the plurality of radar signals is received by an associated antenna of the plurality of antennas. The plurality of processed radar signals are digitally beamformed for at least one beam direction, thereby forming a plurality of beamformed radar signals. The plurality of beamformed radar signals are summed from the plurality of antennas per beam direction.

Abstract: A modulator operable to control an oscillator is described. The modulator can include a memory that stores oscillator control values and a bit streaming block. The bit streaming block can generate a bit stream based on the oscillator control values and transmit the bit stream to the oscillator to control an oscillation frequency of the oscillator. The modulator can also include a bit streaming loader (BSL). The BSL can receive one or more of the oscillator control values from the memory, generate one or more corresponding bit values based on the one or more of the oscillator control values, and provide the one or more bit values to the bit streaming block. The bit streaming block can then generate the bit stream based the one or more bit values generated by the BSL.
