ABSTRACT:
An apparatus and method for frequency translation of true time delay signals in a phased array radar system is provided. A local oscillator signal is true time delayed or modulo 2.pi. phase shifted and then mixed with a true time delay beamsteering signal from a true time delay circuit to produce a frequency translated transmit signal which is supplied to an antenna element. A receive signal received by an antenna element is mixed with a true time delayed or modulo 2.pi. phase shifted local oscillator signal to provide a frequency translated receive signal. The frequency translated receive signal can then be passed through a true time delay circuit and other subsequent processing circuitry. The frequency translation permits higher frequency transmit and receive signals to be used with lower frequency true time delay devices.
