SAR and pulse variations

Started by Unknown May 2, 2006
Hi,

I have a question regarding radar/SAR and pulse
variations / multifrequency signals.
Are there any specific advantages of using
pulse diversity in range measurments, i.e. to
illuminate the same reflectors using for example two
different pulses ? Or there is little to gain from that ?
   
Any reference will be highly appreciated.
   
Thanks.

Are you speaking of frequency hopping between pulses to non-overlapping 
frequency bands???

If so, then the bear in mind that clutter decorrelates with different 
frequency bands...

However, stepped frequency chirps can be employed for range resolution...

Can you be more specific as to what you mean???
