Abstract
A method of determining a radar receiver path, comprising the steps of: obtaining a transmitter position; obtaining a target position and velocity; obtaining a radar receiver position and velocity; determining a transmitter aspect angle gradient, a transmitter aspect angle time derivative and a transmitter co-state vector time derivative; determining a target aspect angle gradient, a target aspect angle time derivative and a target co-state vector time derivative; generating a radar platform heading variable, and a group of differential variables over a defined time span; inputting the group of differential variables into a differential equation solver; receiving a group of possible headings for the radar receiver path; and finding an optimum radar receiver path from the group of possible headings.
