class T_remove_radar: total=2.08e+009, N=1, <>=2.08e+009, min=2.08e+009, max=2.08e+009

Although I understand the need to remove local radar signals, especially when in a band allocated to radiolocation, why do we automatically remove ALL radar?

On the matter of radar, I hold that all civilizations that discover radio, will soon discover radar. I also hold that regardless of advances in that civilization, radar will never outlive it's usefulness.

Communications signals may go from analog to some form of digital, but the need to track flying or orbiting objects will remain. Pulsed CW radar and swept radar should, for any civilization remain both indefinitely, and at high power output.

Shouldn't we be looking for radar in bands not allocated to radiolocation on Earth?

Although it is called radar removal, in actuality it is RFI removal. The application checks the data for abnormal characteristics and replaces those sections.

IMO it is effectively a check whether the receiver front end has been driven into nonlinearity by excessive signal strength. If an e.t. mother ship were on the Moon and using radar to develop topographic maps of Earth, I guess Astropulse wouldn't detect that. But more seriously, I think it's possible that Astropulse might miss a sufficiently strong transient radio pulse such as the one pictured on http://setiathome.berkeley.edu/ap_info.php.
