Abstract: A system and a method are disclosed for proximity detection using a phased antenna array including multiple antenna elements. A method includes transmitting, via a first antenna element and a second antenna element among the multiple antenna elements, a transmission signal; determining, for the first antenna element, a first power of a first injected signal and a second power of a first reflected signal corresponding to the transmission signal; determining, for the second antenna element, a third power of a second injected signal and a fourth power of a second reflected signal corresponding to the transmission signal; calculating, for the first antenna element, a first power metric based on at least one of the first power of the first injected signal or the second power of the first reflected signal; calculating, for the second antenna element, a second power metric based on at least one of the third power of the second injected signal or the fourth power of the second reflected signal; comparing the first power metric with a first threshold value; comparing the second power metric with a second threshold value; and determining whether an object is detected within a proximity range of the phased antenna array, based on the comparison of at least one of the first power metric with the first threshold value or the second power metric with the second threshold value.
