4.8 - Acquisition search space

[@sandhillstudio1487]

5:35-5:40 may be the best description of acquisition search spaces I've ever heard.

The 2-D planar Doppler shift analysis is excellent for first principles though limited because it neglects the impact of Earth rotation relative to the inertial reference ECI; the effect is clearly appreciated with use of 3D vector kinematics analysis (basic vector Mechanics) assuming the receiver is stationary in ECEF coordinates.

The search animation is a bit off. You would normally search from the centre outwards because the doppler is normally reasonably low. It is o ly high in a fast moving aircraft.
