Embodiment Construction
[0105] The proposed devices 100, 101, 102a and 102b perform calculations of distances and angles of obstacles. The device 100 allows additionally and alternatively detection of parking obstacle vibrations, enabling detection of living beings if vital signs are detected.
[0106] Entity 100 is capable of three different modes of radar operation:
[0107] · FMCW operations for distance calculations;
[0108] · CW mode for parking obstacle angle calculation, which has a set of power detectors and is optional;
[0109] • Doppler type operation in CW mode for vibration detection.
[0110] The proposed invention has in the entity 10 a fractional-N phase-locked loop capable of handling the complete operating frequency band, which is adjustable allocated for the operation of the device. For the 77-81GHz automotive frequency band, the frequency-division phase-locked loop (PLL) addresses the full 4GHz bandwidth, which enables high-resolution bandwidth without the need for special dig...
