Proposal Type: Regular
General Category: Terrestrial Aeronomy
Sub-Category: Radar
Observation Category: Ionosphere
Total Time Requested: 35 Hours
Proposal Title: Ionospheric E ects on Coherent Integration in Satellite Tracking
ABSTRACT:
This proposal describes a radar experiment in which satellites with precisely known orbits will be illuminated and
received by di erent UHF, L-band, and X-band radars, including the Arecibo UHF radar in Puerto Rico, the
Millstone Hill UHF and L-band radars, and the Haystack X-band radar, all located in Westford, MA. The
motivation for this experiment is to explore the e ects of the ionosphere on coherent integration times at di erent
frequencies. Longer coherent integration times are becoming more desirable due to the increasingly smaller sizes of
satellites, and the possibility of a satellite break-up in geosynchronous orbit.

Atmospheric Observation Instruments:
Ionosonde
Description of Observer Equipment: Geodetic quality GPS receivers for TEC measurement s will be
provided by Lincoln Laboratory. The goal would be install one or perhaps two closely space GPS
receivers near the radar site. These receivers would sample GPS data at high rates (<1 sec).
Special Equipment or setup: none

RFI Considerations
Frequency Ranges Planned
We are interesting in receiving:
435-440 MHz
1295 MHz
10 GHz
This proposal requires coordination with Punta Salinas radar within the band 1222-1381 MHz..
This proposal requires coordination with AFTWF within the band 425-435 MHz.
