Constructor Detail

GraphPlanSearchPlanner

public GraphPlanSearchPlanner(GeoArea searchArea,
                              double S,
                              double PD,
                              double[] startPosit)

Creates a new instance of AStarSearchPlanner

Parameters:

searchArea - geographic area that is to be searched

S - sensor sweep width as defined in NWP 3-22.5 (SAR TACAID)

PD - required single-search probability of detection of the search

startPosit - double[2] defining the vehicle's position at the beginning of the search

Method Detail

setTrackSpacing

public double setTrackSpacing()

Computes and sets the track spacing to achieve the desired 1-search probability of detection The method uses the formula PD = 1 / (1 + 0.25 * (1 / C)) where C is the coverage factor

Returns:

value of computed track spacing

setSweepWidth

public final void setSweepWidth(double value)

Sets the sweep width (defined in NWP 3-22.5 SAR TACAID) of the search

Parameters:

value - new sweep width value (meters)

setRequiredPD

public final void setRequiredPD(double value)

Sets the required single-search probability of detection of the search

Parameters:

value - new required probability of detection

main

public static void main(String[] args)

Main method for troubleshooting only

Parameters:

args -
