METHODS AND APPARATUS FOR PROVIDING TARGET ALTITUDE ESTIMATION IN A TWO DIMENSIONAL RADAR SYSTEM

摘要

Method and apparatus to track a contact using a sensor in a two-dimensional radar system, determine a closest point of approach (CPA) for the contact, determine a time to closest point of approach (TCPA) for the contact, and estimate 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).
