摘要： A system for determining a level of angle random walk (ARW) associated with a fiber optic gyroscope (FOG) includes first and second photodiodes. The first photodiode is configured to receive a first light signal from a light source associated with the FOG. The second photodiode is configured to receive a second light signal from a fiber optic coil associated with the FOG. First and second analog-to-digital converters (ADCs) are operable to respectively convert the first and second light signals into corresponding respective first and second digital signals. A digital relative-intensity-noise (RIN) subtraction element is configured to receive the first and second digital signals and output a third signal based on the first and second digital signals. An electronic device is configured to determine a first noise level associated with the third signal, and determine the ARW level from the first noise level.

摘要： A gyroscope for determining an angular rate output. The gyroscope includes a first demodulator configured to demodulate an angular rate measurement at a first bias modulation frequency to determine the angular rate signal and a second demodulator configured to demodulate the angular rate measurement at a second bias modulation frequency to provide a signal with ARW information. The gyroscope further includes an ARW estimator that provides an output that is proportional to ARW that is then stored in a memory. The second bias modulation frequency is an even order harmonic of the first bias modulation frequency.

摘要： The invention is a detection system that provides for background removal from a field of view (FOV) of spectra. A panoramic field of regard may be partitioned into a large number of FOV's. An FOV may include spectra including that of a target substance. Such detection may require removing the spectra other than that of the target. This may amount to removal of the background with an estimated background developed from spectra of one or more FOV's which may be similar to the background of the FOV with the target. An estimation of the background may be a sum of a number of FOV spectra where each spectrum is assigned a weight, the total amount of the weights being one.

摘要： A detection system which provides for continuous background estimation removal from a sequence of spectra. A panoramic field of regard may be partitioned into a large number of fields of view (FOVs). An FOV may have a chemical vapor cloud. The small FOV may maximize detection of the cloud. Such detection may require removing the spectral characteristics other than that of the target cloud. This may amount to removal of background spectra with an estimated background developed from one or more FOVs which may or may not be similar to the background of the FOV with the target cloud. A number of estimated background spectra of the other FOVs may be used individually to greatly increase the detection probability of the target chemical.

摘要： A system and method are provided for the determining of the potential effect(s) that a degraded system, subsystem, or component may have on the overall capabilities of a vehicle or other system, and any mitigating actions that may need to be taken. Mission-related capabilities of the system are decomposed into a plurality of lower-level capabilities that have an impact on the mission-related capabilities. One or more faults that have an impact on at least one of the lower-level capabilities are mapped to appropriate lower-level capabilities. The lower-level capabilities to which the one or more vehicle faults is mapped are computed, and values of the mission-related capabilities are computed from each of the lower-level capabilities.

摘要： A system and method for determining the response capabilities of a control effector are provided. Command data and sensor data associated with the control effector are processed to generate control effector health data representative of control effector health. The control effector health data are processed in a reasoned. The reasoned is configure to selectively indict and clear one or more faults, determine one or more failures that cause indicted faults, and determine, based on the one or more determined failures, a usable range of control effector commands to which the control effector can respond.
