Various cross-range resolution techniques applied to an eight-channel 77GHz sensor

Different radar imaging algorithms have been developed and applied to an experimental 77 GHz eight-channel FMCW (Frequency Modulated Continuous Wave) sensor. The sensor uses a single TX antenna and an eight beam RX antenna. The RX antenna provides different beamwidths by the use of dielectric radiators as feeds. Both antennas are realised as planar folded reflectarrays.
