ESTIMATION OF AIRCRAFT TRAJECTORY FROM ITS MOTION USING KALMAN TRACKING FILTER

% Generate a Target and define its motion:
target1 = [zeros(3,11)
          zeros(1,6) 6 7 zeros(1,3)
          zeros(1,5) 6 6 7 zeros(1,3) % Target is a pointd triangle sign 7 by 5 pixels across
          zeros(1,3) 6 6 6 6 7 zeros(1,3)         %  with an intensity of 6 (S/N ratio is ~4).
          zeros(1,5) 6 6 7 zeros(1,3)         % The total target image is made on an 11x11 grid to
          zeros(1,6) 6 7 zeros(1,3)
          zeros(3,11)];                   %  allow the image to be interpolated without error.

target_velx = 3+.9*randn(1);                 % target velcoity in x direction in pixels per second
target_vely = 4+.9*randn(1);                 % target velocity in y direction in pixels per second
target_x_initally = framesize/2-13; % the target is initially in the left upper portion of the frame in x
target_y_initally = framesize/2-13; % and in y
