Interplanetary Medium, Radio Lines: Ism
Scientific paper
The effect of the interplanetary and interstellar media upon a low-frequency space array (300 kHz-30 MHz observing frequency, baseline lengths up to 100-200 km) has been quantified. A new feature of these calculations is the impact of angular broadening by the interstellar medium upon temporal coherence. inclusion of this feature demonstrates that the media effects upon observations with such an array will be much less serious than indicated by earlier studies. The coherence loss from the interplanetary medium wilt be minor for a wide range of observing parameters. The differential Faraday rotation over a baseline is negligible, but the Faraday depolarization over even the smallest sources will be large at most observing frequencies. Therefore, the use of linear feeds will not result in degradation of imaging capability.
