The below statement surprised me.  That is not how noise blanking 
normally works; normally it will suppress  any wide band pulse.  The 
typical arrangement uses a high bandwidth, low delay, path, to detect 
the pulse.  It can then mute the signal path by the time the pulse gets 
through the narrower filters on the main path.  That will happen with 
single, or randomly spaced spikes.
