In numeric terms, it corresponds to around 0.0001 m2 of radar cross section (RCS). This is around 100,000 times smaller than the radar cross section … RCS reduction is chiefly important in stealth technology for aircraft, missiles, ships, and other military vehicles. With smaller RCS, vehicles can better evade radar detection, whether it be from land-based installations, guided weapons or other vehicles. Reduced signature design also improves platforms' overall survivability through the improved effectiveness of its radar counter-measures. pir lights battery
