The validity of this result is conditional, depending on the cloud profiling radar and radio astronomy antenna patterns. Hence, updates will be necessary as better knowledge on the antenna patterns become available. Addition of a notch filter into the RA receiver band would permanently prevent RA observations at frequencies covered by the filter. Furthermore, WP7D suggests that to prevent the proliferation of space-based radars, such an allocation be restricted to cloud profiling radars, possibly through a footnote to the Radio Regulations. Finally, concerning the transmissions of such systems, a pulsed signal would have lower impact on RA observations than a chirp-type transmission.
Measurement of distance is one of the most fundamental studies in astronomy.
Around 94.0-94.1 GHz no such strong maser lines exist. 14 degrees from nadir of the satellite. This would eliminate the possibilities of damaging the SIS receiver and a largest part of saturation occurrences.
