Does anyone know of such a thing as a 'Standard Radar data tape format'
and hopefully some source code to read such a thing ? Thanx in advance.

There's no such thing - tape formats vary with sensor and data source, like 
most other remote sensing data. Makes life interesting. I can read a number
of the formats - drop me a note offline and let me know what you are interested
in and I will try and help.

I did some work with the Naval Weapons Center in Va. awhile back,
and they were dumping tons of emitter data to a tape while flying
through various areas.  Is this what you are asking about?

	We collect a LOT of data that we analyze as well as package
and send to others. Also we receive a lot of radar data (SAR imagery)
from others to analyze. Generally, we store and send data in "8-8-4"
format, which is 8 bits of real, 8 bits of imaginary, and 4 bits of
exponent. We have received radar imagery in every format imaginable:
two that stick out are complex integer data (unscaled) and data that 
has already been detected and is in 8 bit gray scale (or PIX) format. 
As far as I know, there is no single standard radar format; everyplace
I know likes to store their I and Q differently.
