GURPS: VE2 AESA Confusion

[trux]

Hi all,

On GURPS: VE2 pages 51-52 are the rules for radar and ladar systems.

Page 51 states that the

A. A radar cannot have both Surface and Air Search options.

B. The low-res imaging radar is incompatible with AESA, high-res imaging radar mode, and ladar mode.

C. The high-res imaging radar is incompatible with AESA, low-res imaging radar mode, and ladar mode.

D. The ladar is incompatible with AESA, low-res imaging radar mode, and ladar mode.

E. Active Electromagnetic Sensor Array (AESA)
1. gives the "radar" the ability to switch between search radar, low-res imaging, high-res imaging radar mode, and ladar mode.

2. It is incompatible with either imaging radar or ladar options.

Items A through E has me totally confused about the AESA option.

Items B through D clearly states that they cannot be used with the AESA.

Item E1, in my opinion, states that the AESA allows the radar to switch between the other options and item E2 states that the system is incompatible with imaging or ladar?

Does or doesn't AESA allow integration of all the radar options into a single package?

AESA can function as any of the other types. It cannot take modifiers for those other types.

I'm still not clear about how AESA works so here what I came up with, without showing the math, my paper calculations aren't easy to read ;-):

TL 11 AESA/8 - Radar/11, Air Search/8+, High-Res Imaging/L7, Ladar/8
Range: 1,000 mi
Radar/High-Res Imaging Scan 29/19
Weight: 18.75 lbs.; Volume: 0.375 cf; Cost 3.125,000; Power: 12.5 kW

TL 11 Radar: 0.25 lb per mile, therefore 250 lb for 1,000 miles
AESA: x1.5 = 375 lb
Volume: divide by 50 = 7.5 cf
Cost: 125 $ x ((1,000/5)+100) x5 = 187,500 $
Power: 0.25 kw x 1,000 = 250 kw
Scan 29

You can use it as Radar with range 1,000 miles / scan 29, or as Ladar with range 500 miles / scan 27, or as Low Resolution Imaging Radar with range 500 miles / scan 27, or as High Resolution Imaging Radar with range 20 miles / scan 19.

Hi Pomphis,

Thanks for the reply, letting me know I'm on the right track and catching that my math was off from the start.

See I told you I couldn't read my own hand written calculations. Thanks for the help. :-)
