Abstract
Embodiments are directed to operating an analog signal processing circuit to emulate a Rotman lens. The analog signal processing circuit applies a plurality of time delays to a plurality of signals associated with a plurality of beam ports. The analog signal processing circuit forms a plurality of output beams for transmission by a plurality of array ports included in an array based on the time delayed signals by summing the time delayed signals. The time delays are based on a direction of transmission of the output beams.
Claims19
A method for operating an analog signal processing circuit to emulate a Rotman lens, the method comprising:
- applying, by the analog signal processing circuit, a plurality of time delays to a plurality of signals associated with a plurality of beam ports;
- and
- forming, by the analog signal processing circuit, a plurality of output beams for transmission by a plurality of array ports included in an array based on the time delayed signals by summing the time delayed signals,
- wherein the time delays are based on a direction of transmission of the output beams.
A system for emulating a Rotman lens, comprising:
- a plurality of beam ports;
- an array comprising a plurality of array ports;
- and
- an analog signal processing circuit configured to form an output beam for transmission by the array ports based on applying a plurality of time delays to a signal from at least one of the beam ports, where the time delays are selected in accordance with a selected direction for transmission wherein the array is configured to simultaneously transmit multiple output beams by summing time delayed signals from multiple beam ports at each array port.
