First Claim
Patent Images
1. A method, comprising:
- tracking a contact using a sensor in a two-dimensional radar system;
determining a closest point of approach (CPA) for the contact;
determining a time to closest point of approach (TCPA) for the contact;
estimating an altitude for the contact from the closest point of approach (CPA) and a cross line of sight distance during the time to closest point of approach (TCPA).
