Abstract
An apparatus that includes a phased array configured to monitor a broad bandwidth with low rate ADC achieving sub-Nyquist rate sampling with 100 percent duty cycle. The phased array includes a plurality of phased array elements. Each of the phased array elements are inserted with a non-uniform true time delay to enable simultaneous measurement of an AOA and a frequency of an incident RF signal.
