MDC Configuration Working Group Meeting
Date: Monday, 14 September 1998
Time: 11:00 am EDT (9:00 am Socorro, 8:00 am Tucson/CA)
Phone: (804)296-7082 (CV SoundStation Premier Conference phone).
Agenda
------
1) Update on current status
a) Kogan: Minimax program for synthesized beam sidelobes.
Program features:
-optimize for shared stations (Memo 226)
-restricted geometries allowed (Memo 217, 212)
-restricted topographies allowed (Memo 202)
b) Other Memos:
-Webster nested rings/triangles (Memo 214)
-Conway spiral geometries (Memo 216)
-Holdaway cost-benefit analysis
for number of configs (Memo 199)
2) D array
a) Kogan optimization for worst sidelobe vs. D array diameter
(Memo 217). Assumes N=36, D = 10m, minimum spacing = 12.8m
(current = ?).
Array Size (m) 78 82 86 90 96
Worst Sidelobe .390 .283 .125 .108 .102
b) Future work: optimize for filled subarrays with NS elongations
of 1.2, 1.6, 2.9. Want to include short EW spacings.
Optimize for shared stations where possible.
3) C, B, A arrays
a) Current design philosophy: Nested rings/triangles
b) Simulations
