Abstract
A method for operating a multifunction laser radar system including receiving a target state corresponding to parameters of a target, selecting a mode of operation from a plurality of modes of operation for the laser radar system based on the target state, receiving returns reflected by the target via the laser radar system operating in the selected mode of operation, processing the returns to calculate at least one target measurement, and determining a filtered target state based on the at least one target measurement.
Claims20
A method for operating a multifunction laser radar system, comprising:
- receiving a target state corresponding to parameters of a target, the target state comprising information of a target type of the target from among multiple possible target types;
- selecting a mode of operation from a plurality of modes of operation for the multifunction laser radar system based on the target state;
- receiving returns reflected by the target via the multifunction laser radar system operating in the selected mode of operation;
- processing the returns to calculate at least one target measurement;
- and
- determining a filtered target state based on the at least one target measurement using a target range and a target range rate in a target state estimator, wherein determining the filtered target state based on the at least one target measurement includes using the target state estimator configured to provide the filtered target state based on a covariance between the target range and the target range rate.
A multifunction laser radar system, comprising:
- a transmitter configured to generate laser pulses and to direct the laser pulses towards a target;
- a receiver configured to collect light reflected from the target;
- and
- a controller coupled to the transmitter and the receiver and configured to:
- receive a target state corresponding to parameters of the target, the target state comprising information of a target type of the target from among multiple possible target types;
- select a mode of operation from a plurality of modes of operation for the multifunction laser radar system based on the target state;
- receive returns collected by the receiver while the multifunction laser radar system is operating in the selected mode of operation;
- process the returns to calculate at least one target measurement;
- and
- determine a filtered target state based on the at least one target measurement using a target range and a target range rate in a target state estimator, wherein the controller is configured to use the target state estimator configured to provide the filtered target state based on a covariance between the target range and the target range rate.
A non-transitory computer readable medium comprising code that, when executed by at least one processor, controls a laser radar system to:
- receive a target state corresponding to parameters of a target, the target state comprising information of a target type of the target from among multiple possible target types;
- select a mode of operation from a plurality of modes of operation for the laser radar system based on the target state;
- receive at least one return reflected by the target via the laser radar system operating in the selected mode of operation;
- process the at least one return to calculate at least one target measurement;
- and
- determine a filtered target state based on the at least one target measurement using a target range and a target range rate in a target state estimator, wherein determining the filtered target state based on the at least one target measurement includes using the target state estimator configured to provide the filtered target state based on a covariance between the target range and the target range rate.
