A short introduction to electronic beam steering is given and different approaches for angle resolving imaging are shown. Two sensors, a mono-static 80 GHz radar sensor and a polarization resolving bistatic 94 GHz radar module are presented which can be valuable elements of sensor-suites for modern UAV based imaging and surveillance and autonomous operation.en621conference paper
