Abstract

Route search planner methods and systems are described. In an embodiment, a probability map can be generated from previous sensor scans combined with a projected target location of relocatable targets in a target area. A route can be generated by a route generator, based at least in part on the probability map, and based on optimal system performance capabilities utilized to search for at least one of the relocatable targets. A search manager can then assign an evaluation criteria value to the route based on route evaluation criteria, and compare the evaluation criteria value to other evaluation criteria values corresponding to respective previously generated routes to determine an optimal route. The search manager can then determine whether to generate one or more additional routes and assign additional evaluation criteria values for comparison to determine the optimal route.

Claims

1. A method, comprising:

generating a probability map from previous sensor scans combined with a projected target location of one or more relocatable targets in a target area;

generating a route by which to search for at least one of the relocatable targets, the route being generated based at least in part on the probability map;

assigning an evaluation criteria value to the route based on route evaluation criteria, the evaluation criteria value being comparable to one or more evaluation criteria values corresponding to respective previously generated routes to determine an optimal route; and

determining whether to generate one or more additional routes and assign additional evaluation criteria values for comparison to determine the optimal route.

2. A method as recited in claim 1, wherein the route is generated as a flight path for an airborne platform to search and locate the at least one relocatable target.

3. A method as recited in claim 1, further comprising determining that the optimal route meets a conditional probability threshold based on the route evaluation criteria that includes commit logic which indicates whether to commit to the at least one relocatable target.

4. A method as recited in claim 1, wherein the route is generated based on optimal capabilities of sensors and autonomous target recognition algorithm processing.

5. A method as recited in claim 1, wherein the probability map is generated at least in part from the previous sensor scans of a region in the target area, and wherein the route is generated based at least in part on the probability map, and based on at least one of an initial route heuristic;

a distance offset.

6. A method as recited in claim 1, further comprising developing the projected target location based on target characteristics combined with a previously known target location projected into the future by a future time input.

7. A method as recited in claim 6, further comprising:

receiving a targeting input as at least one of;

a sensor scan input;

a data link input; and

determining the previously known target location from the targeting input.
