Abstract :
An X-band FMCW sensor is developed with beam-scanning capability to reliably detect the vehicles with different shapes. Two-element transmitting antenna array is designed with single phase shifter and an unequal power divider to reduce the cost and achieve compact size of 4.5 cm × 4 cm. Experiments successfully confirm precise identification of the incoming vehicle and its occupancy.
