N-scan

N-display

N-display
In radar, a display similar to the K-display, in which the target appears as a pair of vertical deflections or blips from the horizontal time base. The relative amplitude of the vertical deflections indicates direction; target distance is determined by moving an adjustable signal along the baseline until it coincides with the horizontal position of the vertical deflections. The horizontal control is calibrated in distance. Also called an N-scan, N-scope, or N-indicator.

Any scan order (e.g., Parallel-scan, Zig-Zag scan, N-scan, Fractal-Hilbert-curve) can be adopted in the proposed method.
We implemented Parallel-scan, Zig-Zag scan, N-scan, and Fractal-Hilbert-curve to determine a suitable scan in order to improve compression rate as much as possible.
