Abstract: A system and method for sensor quality detection continuously monitors a context (vehicle state, proximal environmental factors, surrounding environmental conditions) surrounding a vehicle as well as actual sensor output. The system compares actual sensor output with expected sensor output to determine if the sensor has become degraded or if the degradation is due to the surrounding context. Once the system determines the context-based or actual degradation, it determines if the sensor is able to complete an assigned tasking with the degradation within the specific mission-based requirements of the sensor. Should the degraded sensor be unable to complete the task, the system transfers the tasking to a second vehicle equipped with an operational sensor.

Abstract: A radio frequency (RF) transmission line is described. The RF transmission line includes a first ground line, a second ground line, and a signal line disposed on a substrate and forming a coplanar waveguide. A plasma limiter feature is integrated into an internal surface of one or more of the first ground line, the second ground line, and the signal line. The plasma limiter decreases a gap distance between the signal line and the associated ground line. The gap distance is selected, together with a gas pressure, to control a voltage at which the gas within the gap breaks down, targeted at a breakdown power of 1 W across a wide bandwidth. The plasma limiter thus limits a power transmitted by way of the RF transmission line for protecting a sensitive integrated circuit.

The estimated navigation trajectories are generated based on the estimated navigation states.

Abstract: A system for calibrating ESAs calculates a taper based on ESA element coordinates, and stores the taper as a vector matrix of gain values. The gain values are normalized by accounting for known losses by measuring a central element at minimum attenuation. The normalized gain is then a reference for every other element in the array. The other elements are then measured at various attenuations to identify an attenuation to produce the desired gain. The measurements are performed according to a bisection algorithm. Attenuation may be embodied in a set of digital register values.
