A camera assembly (10) for a driver monitoring system (1) is disclosed with glare protection. A cap (16) for at least one LED (20) is provided to define an opening (21) through which a light cone (27) exits. The cap (16) is defined by a pass-through section (17) connected to at least one first sidewall (18) and one second sidewall (19). The first sidewall (18) is higher than the second sidewall (19) and the first sidewall (18) positioned close to the lens (12) of the camera assembly (10).

A radar transceiver (101) arranged to transmit a first waveform in a first frequency band, and a second waveform in a second frequency band different from the first frequency band, wherein the second waveform is configured to be scaled in the time domain compared to the first waveform by an amount corresponding to a difference in wavelength between the first and the second frequency bands, thereby compensating for a difference in phase evolution of a target reflection (125) over time for the first waveform compared to the second waveform.

The present disclosure relates to a radar system (210) for a vehicle (200), comprising a plurality of radar transceivers (202, 203, 204, 205) and a control unit (208). Each radar transceiver (202, 203, 204, 205) is associated with a main pointing direction (PI, P2, P3, P4) and a certain frequency sub-band (A, B, C, D), where the subbands (A, B, C, D) together form a certain dedicated frequency band. The control unit (208) is adapted to:- define heading intervals which divide a full turn interval 0° - 360° into sections,- assign a corresponding sub-band (A, B, C, D) to each heading interval,- determine a present vehicle heading (F), and to- assign a corresponding sub-band (A, B, C, D) to each one of the radar transceivers (202, 203, 204, 205) in dependence of the heading interval that comprises the present vehicle heading (F).

The present disclosure relates to a vehicle radar system (3) comprising a control unit (4) and at least one transceiver arrangement (5), for transmitting radar signals (6) and receiving reflected signals (7), The vehicle radar system (3) is adapted to identify at least one ground stationary target object (8), and to follow the ground stationary target object (8) for a plurality of times (t<1>-t<5>). For at least two different values of a parameter (v<host>, ω, θ<GND>) related to, or affected by, vehicle dynamics or vehicle statics for a host vehicle (1), the control unit (4) is adapted to calculate a coherently integrated complex signal representing the detected ground stationary target object (8<t1>, 8<t2>, 8<t3>, 8<t4>, 8<t5>) for the plurality of times (t<1>-t<5>) using said parameter (v<host>, ω, θ<GND>) such that a resulting signal magnitude (A<1>, A<2>, A<3>, A<4>, A<5>) is obtained. The control unit (4) is further adapted to compare the resulting signal magnitudes (A<1>, A<2>, A<3>, A<4>, A<5>), and to choose the parameter value (v<host3>) that is associated with the highest signal magnitude (A<4>, A<t5>) as the most correct parameter value.
