Abstract
A radar system () is described including a transmitting assembly (), a receiving assembly (), a control unit () and a signal processing unit (). The transmitting assembly () receives an input signal () and transmits an incident radar signal (). The transmitting assembly () includes a Rotman lens () having a lens cavity (), a plurality of beam ports (), a plurality of array ports () and a patch antenna assembly (). The lens cavity () has a lens gap (h) between 10 microns to 120 microns, and preferably 40 microns to 60 microns. The patch antenna assembly () includes a plurality of antenna arrays () operable to receive a plurality of time-delayed, in-phase signals from the Rotman lens () and to transmit the incident radar signal () towards a target (). The receiving assembly () receives a reflected radar signal () and produces an output signal. The signal processing unit () compares the input signal () to the output signal and implements an algorithm determining the range, velocity and position of the target ().
