Abstract: Since a typical radar has an antenna with a sharp main beam which is rotating in a regular manner, it is of great interest to examine how much the secondary access to radar will benefit from exploiting the temporal aspect.
In [1, 2], the temporal opportunities of the secondary access to radar spectrum is quantitatively investigated under the assumption that the antenna pattern and the rotation of the radar are perfectly known to the WLAN devices. It is observed that opportunity of secondary access improves significantly when the temporal aspect of radar is exploited. Practical ways of implementing the temporal secondary access are thus key remaining research challenges.
