Systems and methods for radar signature modeling using a rotating range profile reduced-order model

A method of performing a radar sensor simulation, comprising:

• receiving a radar model for a target objects within a simulation environment;
• identifying a target aspect angle for the target object relative to a radar sensor within the simulation environment;
• identifying a corresponding radar return strength from the radar model for the target object using the target aspect angle;
• and
• scaling the radar return strength based on a position of the target object within the simulation environment relative to the radar sensor to generate a simulated radar return value.

A system for generating a reduced-order high fidelity radar model for a target object, comprising:

• a radar system simulator configured to,
• generate a simulation model representing a radar system and a target object with a reference distance between the radar system and the target object, and a target aspect angle identifying an angular position of the target object in relation to the radar system;
• simulate interaction of the radar system with the target object to generate a range profile for the target object at a target aspect angle identifying an angular position of the target object in relation to the radar system, the range profile identifying a radar return strength for the reference distance, the range profile generated based on a time domain range profile converted from a frequency domain range profile;
• increment the target aspect angle;
• repeat the simulating and incrementing operations until range profiles are generated for the target object at a plurality of target angles t;
• and
• accumulate the range profiles at the plurality of target angles to generate the reduced-order high fidelity radar model for the target object.
