Actually, I stand by my ruling that it only works out to 15m as a cyberware scanner. I've actually got some experience with millimeter wave scanners in the airline security industry. They're typically referred to as "backscatter" sensors. They shoot a specific high-frequency wavelength at the target at a really high power and it can penetrate clothing to see things underneath when the reflected energy is measured. Since it's a high-frequency high-power system, it needs to be very directed and the range is not very far. A standard radar system has a much longer wavelength, and therefore can go much further using a given amount of energy. But as the wavelength increases the resolution decreases. Hence the difference in the two ranges.
The fact that a portable scanner and an integrated cyberware scanner have a big price difference is immaterial, as this is the case with ALL the optical devices. Price out a pair of Rating 4 goggles versus a comparable set of cybereyes and the price difference is staggering.
yap but the radar uses different waves. millimetre and ultra-wideband terahertz. Admittedly I not relay in the mood to look them up at 4:00 AM, but you can rule as you think is correct in your games, so can Sent here. we had this sensor a Gray area for a while now and you are welcome to join the discussion.
By the way, the problem of the rang of the Milimter is not the wave length, but the power, it has not got much of it and it scatters too much so only a fraction of the waves return limiting the range.
Edit:
OK teraqherz is actually called Sub milimeter wave as well so it is even more prcise then the one we are using today and UWB is the delivery system.
as far as I understand these wavs go the full distance, but it's getting really late, my shift starts in 4h and I will finish up tomorrow.
