Embodiment Construction

[0017] The following detailed description of the embodiments refers to the accompanying drawings that illustrate specific embodiments of the present disclosure. Other embodiments having different structures and operations do not depart from the scope of the present disclosure. The same reference numerals may refer to the same parts or components in different drawings.

[0018] The use of specific terminology herein is for convenience only and should not be taken as limitations with respect to the described embodiments. For example, words such as "near", "far", "top", "bottom", "top", "bottom", "left", "right", "horizontal", "vertical", "up", and " Words such as "downward" merely describe the configuration shown in the figures or are used with reference to the relative position of the orientation of the depicted figures. Because components of an embodiment may be positioned in many different orientations, directional terminology is used for purposes of illustration and not li...

Abstract

A multi-function radio frequency (RF) system may include a shared phased array antenna subsystem for transmitting and receiving radar signals and communications signals. The system may also include an integrated electronics package configured for controlling operation of the shared phased array antenna subsystem. The integrated electronics package may include a modulator / demodulator subsystem. The modulator / demodulator subsystem may include a radar module that is selectively coupled to the shared phased array antenna subsystem for transmitting and receiving radar signals. The radar module is configured to transmit and receive radar signals through the shared phased array antenna subsystem. The modulator / demodulator subsystem may also include a communications module that is selectively coupled to the shared phased array antenna subsystem for transmitting and receiving communications signals. The communications module is configured to transmit and receive communications signals through the shared phased array antenna subsystem.

Description

technical field [0001] The present disclosure relates to antenna arrays, radar systems, and communication systems, and more particularly, to multifunctional shared aperture arrays or shared antenna arrays. Background technique [0002] Current radar and communication systems or subsystems are implemented as separate systems each with separate apertures and electronics. This solution requires increased weight and greater surface area for separating the apertures. In some applications, this is acceptable. However, having multiple discrete functions and systems is not practical when such multifunctionality is expected on platforms with smaller surface area and weight constraints, such as unmanned aerial vehicles (UAVs). In addition, the separate systems also take longer to offload sensor data, such as received and processed by a radar system, and then offloaded or sent to another location (eg, from a UAV to a ground station) via a communication system. This reduces the abili...
