Pseudo-Range Estimation From A Passive Sensor
Publication/Patent Number: US2020104609A1 Publication Date: 2020-04-02 Application Number: 16/143,866 Filing Date: 2018-09-27 Inventor: Clothier reece alexander   Williams, Brendan Patrick   Hegarty-cremer, Solene Gabrielle Doreen   Assignee: The Boeing Company   IPC: G06K9/00 Abstract: A rough initial estimate of Line of Sight range (“pseudo-range”) is generated essentially immediately following the detection of an object by a passive sensor on a vehicle. The data are combined with prior detection likelihood and prior performance models for the sensor. These comparisons generate a posterior probability distribution of pseudo-range estimates. A pseudo-range estimate is derived from the probability distribution and output for use in detect and avoid decision-making and action planning. The pseudo-range estimate can be updated to improve its accuracy, such as by using a recursive filter (e.g., a Kalman filter). Other information, such as current atmospheric data, or known (or likely) vehicular activity in the region and at the current time, can be used in addition to the vehicle's spatial and temporal location, to improve accuracy.

PSEUDO-RANGE ESTIMATION FROM A PASSIVE SENSOR

METHODS AND SYSTEMS FOR ATTENUATING THE EFFECTS OF TURBULENCE ON AIRCRAFT
Publication/Patent Number: WO2015179905A1 Publication Date: 2015-12-03 Application Number: 2015000326 Filing Date: 2015-05-29 Inventor: Watkins, Simon   Clothier reece alexander   Mohamed, Abdulghani   Assignee: RMIT UNIVERSITY   IPC: G05D1/00 Abstract: A method and system is provided for attenuating the effects of turbulence on an aircraft. The method includes: (a) providing at least one sensor on or forward of a leading surface of the aircraft; (b) sensing a flow disturbance caused by turbulence approaching the leading surface to generate sensed input; (c) transmitting the sensed input to a control system; and (d) actuating one or more flight control surfaces to counteract an aircraft perturbation that is anticipated to occur in response to the sensed flow disturbance; wherein the flow disturbance is sensed ahead of the leading surface of the aircraft so that the flow disturbance is detected substantially before the aircraft perturbation is initiated by the flow disturbance.
