Abstract
A computer-implemented radar simulation method is provided for directing a radar beam to a target. The method includes receiving target position from the target; computing target coordinates in a select frame of reference; inserting random noise error into the target coordinates as accuracy degradation to represent at least one radar performance characteristic; providing the accuracy degradation into the frame of reference; and directing the radar beam by the accuracy degradation towards the target.
Claims18
A computer-implemented radar simulation method for directing a radar beam to a target, said method comprising:
- receiving target position from the target;
- computing target coordinates in a select frame of reference;
- inserting random noise error into said target coordinates as accuracy degradation to represent at least one radar performance characteristic;
- providing said accuracy degradation into said frame of reference;
- and
- directing the radar beam using said accuracy degradation towards the target.
An automation processor for modifying positional information of a target for a test radar that directs a beam towards said target to simulate a non-test radar that has at least one performance characteristic, said processor including:
- a receiver for receiving the positional information of the target;
- a converter for converting the positional information into reference frame coordinates selected for the test radar;
- an error generator for producing accuracy degradation comprising Gaussian noise based on the performance characteristic;
- a signal integrator for integrating said accuracy degradation to said reference frame coordinates as noisy coordinates;
- and
- a transmitter for submitting said noisy coordinates to the test radar for directing the radar beam.
