Proposal Identication No.: S1145 Date Received: 1998 -Apr-14 11:17:51
Technical Page
Proposal Type: Large
General Category: Astronomy
Sub-Category: Spectroscopy
Observation Category: SETI
Total Time Requested: 2400 Hours
Proposal Title: Project Phoenix: SETI Targeted Search Observations
ABSTRACT:
This is a search for radio signals transmitted by another technology from the vicinity of nearby solar-type stars.
The dual polarization search detects narrowband CW and pulsed signals, that may be drifting slowly, over 1.3 to
3.0 GHz. 300 second observations can detect 1x10 11 W EIRP transmitters at 100 ly. Candidates are immediately
followed up by a pseudo-interferometer formed by Arecibo and the Lovell Telescope to discriminate against RFI.

Instrument Setup
430 G L-wide S-low
Atmospheric Optical Instruments:
Description of Observer Equipment: 15 ton backend equipment van (MRF), 45 KVA transformer, 2
IF racks, down converter rack, 3 X-terms/CPUs, drives, MAC, 5 KVA UPS, FAX, various hubs and
modems for data communication. Inplace ber network. Network equipment for 64 kbs WAN to Jodrell
Bank.
Special Equipment or setup: various co-ax switches and ampliers/lters for quick change, to get
spectral power density and dynamic range to Phoenix values. Concrete pad for MRF with power, ber,
and phone.
Ethernet connection to telescope and receiver control computer and mods to software interface to accept
antenna pointing and receiver tuning commands from Phoenix system.
all recording done on user supplied DAT drives.

This proposal requires Iridium RFI protection at 1612 MHz between 10pm and 6am EST.
This proposal requires coordination with Punta Salinas radar within the band 1222-1381 MHz..
This proposal requires coordination with GPS L3 at 1381 MHz.
This proposal requires coordination with AFTWF within the band 425-435 MHz.
