Abstract: Methods and systems for detecting objects in a three-dimensional space. The method includes emitting, by a plurality of transmitters oriented in a respective plurality of directions, signals to produce uniform millimeter wave illumination of the three-dimensional space. The method includes determining object data including a direction, a phase, and a timing of signals reflected from one or more objects within the three-dimensional space. The method includes detecting, by a processor, the one or more objects in the three-dimensional space based on the object data. The method includes rendering, by the processor, an image corresponding to the one or more detected objects.

Abstract: A system for network agnostic satellite communications includes an antenna configured to receive at least one antenna receive beam including multiple receive carriers multiplexed in at least one of frequency or time. The system further includes a signal processor configured to receive the multiple receive carriers and to extract data from at least one receive carrier of the multiple receive carriers. The system further includes an input device configured to receive at least one desirable communication parameter. The system further includes a control processor designed to determine actual parameters corresponding to the multiple receive carriers of the at least one antenna receive beam. The control processor is further designed to select an optimal receive carrier by comparing the at least one desirable communication parameter to the actual parameters. The control processor is further designed to establish a current communication link with the optimal receive carrier.

Abstract: A tunable filter for adjustable filtering between a minimum frequency and a maximum frequency includes a transmission line designed to transmit a signal and having longitudinal axis. The tunable filter further includes a two-dimensional capacitor array including step-tunable capacitors located along the transmission line, a first dimension of the two-dimensional capacitor array being along the longitudinal axis and a second dimension of the two-dimensional capacitor array being located perpendicular to the longitudinal axis. The tunable filter further includes a controller coupled to each of the step-tunable capacitors and designed to control each of the step-tunable capacitors independently to be in a biased mode or in an unbiased mode based on a desired frequency response of the tunable filter.
