Abstract
A Doppler radar is used to obtain the velocity, altitude, and distance of an aircraft with respect to the radar coordinates. It is shown that the reflected electromagnetic fields picked up by the receiver antenna also contain information on the rotation angle and tilt angle of the aircraft, which could be obtained using a maximum-likelihood estimation algorithm. The electromagnetic signal processing unit estimates the angles of rotation and tilt and the radius of the target modeled as a cylinder using the scattered magnetic field. Specific results showing the application of the estimator are given. >
