Ultra-Tech Quicky: Actively Searching

I got the feeling, someone's tracking meeee!!
A few posts ago I came up with a design system for making your own Passive Visual Sensors. Today I tackle Active Sensors in a new format called Ultra-Tech Quickies wear I tackle gear that only takes a page or two to stat up!


So do you got some bogeys you need to Fox Three but don't have the Active Sensors you need? Then follow me after the jump to see how to design your own!











Use these rules to stat up your own active sensors. See Ultra-Tech pg. 63-66 for all the rules concerning the Active Sensor types covered here. Note that these rules assume you are scanning an 120° arc in front of them (see No Peripheral Vision, Basic Set pg. 151). For sensors that scan 360°, multiply weight and cost by 1.5.

Legal Class is 4 for all Active Sensor expect for Ultrascanners which are LC3 and Tactical versions of these sensors which are LC2.

Ladar/Radar (TL9)
The weight of a given radar or ladar is based on it's range in miles. See Ultra-Tech pg. 64-65 for the rules for Radar and Ladar.

Weight = (10^((LOG10(R/10)×2)+1))/TL

R is the Radar/Ladar range in miles.
TL is 10 at TL9, 40 at TL10, 250 at TL11 and 1,000 at TL12.

Cost = S×Sensors Weight

S is $1,000 for Radar and $2,000 for Ladar.

Terahertz Radar (TL9)
It is figured just about the same way as radar and ladar but with its range is in yards instead of miles. Note that the ranges listed in Ultra-Tech are rounded and at TL9 actually should be 170 yards for the Small Terahertz Radar, 528 for the Medium Terahertz Radar and 1,760 for the Large Terahertz Radar. See Ultra-Tech pg. 65 for the rules for Terahertz Radar.

Weight = (10^((LOG10(R/10)×2)+1))/TL

R is the Terhertz Radar range in yards .
TL is 3,000 at TL9, 12,000 at TL10, 75,000 at TL11 and 300,000 at TL12.

Cost = $2,000× Sensors Weight

Sonar (TL9)
You need to choose if the Sonar is meant for air or water use. Sonar has less range in air and will weigh 10× more then a water based on of the same range. Range is in yards. See Ultra-Tech pg. 65 for the rules for Sonar.

Weight = (10^(LOG10(R))/TL)×Ty

R is the Sonars range in yards .
TL is 200 at TL9, 400 at TL10, 1,000 at TL11 and 2,000 at TL12.
Ty is 1 is water based, 10 if air based.

Cost =Cost = $200× Sensors Weight  




Ultrascanner (TL11^)
When figuring the Ultrascanners range, use its Search Mode range, its range it 1/10th its Search Mode range in other modes. Weight is based on range in miles. See Ultra-Tech pg. 66 for the rules for Ultrascanners.

Ur Example: The Next Generation
Weight = (10^((LOG10(R/10)×2)+1))/TL

R is the Ultrascanners Search Modes range in miles.
TL is 10 at TL11^ and 40 at TL12^.

Cost = $2,000× Sensors Weight

Power
For All Active Sensors except Terahertz Radar and Ultrascanner.
A C cell of equal TL to the Sensors will power it for  (80/Sensors Weight)hrs.

For  Terahertz Radar
A C cell of equal TL to the Sensors will power it for  (100/Sensors Weight)hrs.

For Ultrascanners
A C cell of equal TL to the Sensors will power it for  (40/Sensors Weight)hrs.

A  higher TL power cell will power a given senoser 4× as long per TL higher while a lower TL power cell will power it for 1/4th as long per TL lower. See Ultra-Tech pg. 18-20 for more on power cells.

  1. Good stuff! I'm working with a TL8ish weapon that uses active and passive scanning (hoping to get it out this week but we will see) so I'm having to get up to speed on how the rules work. When I start doing Tib Sun stuff (largely TL9) I'll look to reference this for some of the kit.

    1. TL at TL8 is 0.5 for Radar/Lader, 150 for Terahertz Radar and 10 for Sonar.

    2. Cheers! I may have asked this (and have forgotten), but where do you get TL = ### numbers from? Might be that I am jumping from thing to thing but I'm not sure how that gets figured.

      Fortunately in my case it's a real-world thing, so I'll likely not have to run a formula, but if I make a fictional one I will.

    3. The TL was figured from the fact that active sensors go up in range as their actual TL goes up and was used to figure a constant made the weights line with what has been published.

      The range for active sensors at TL8 listed in High Tech are about 1/20th range of a TL9 one of the same weight listed in Ultra Tech so I just adjusted the constant TL to match.
