OVERVIEW: The HN-401R is a mobile, long range, 2-D surveillance radar operating in the B/C Band.

DETAILS: The HN-401R consists of a large horizontally polarised dipole planar-array. The system employs fully coherent pulse compression techniques and uses a highly stable frequency source. The signal processing system is able to adapt to pulse-to-pulse or burst-to-burst frequency agility and moving target indicator.
Low-azimuth sidelobes are achieved by feeding unequal power.
