Hi All,
Last year I did was working on a uni paper looking at developing a generic
software-defined radar transmitter using GNU Radio as part of a university
submission. The gnu radio list was instrumental to me learning about
Software Defined Radio, getting my USRP N210 up and running and
Hey David,
Thanks very much, your inputs be a great help!

Hi guys,
Thanks
Apologies that copy paste formatting was attrocious..! Data attached in
file.
P.S. earlier I meant to say f1 = 4MHz and f2 = 5 MHz
In the attached data
m1 = 2*f1-f2
m2 = f1
m3 = f2
m4 = 2*f2-f1
thx!

Hi All,
I'm looking at the parts of the XCVR2450 trying to do theoretical gain /
noise calcs.
My first question is... has anyone else done these? Do my numbers seem
reasonable?
Secondly.. I don't know what gain the AD8132 has.. it seems to offer G

Hi Josh,
Sorry for the belated reply!
Yes it says 6GHz on the uhd_usrp_probe but i was just surprised given that
the website said its limit was 5.9GHz.

Hi All,
I'm looking at how suitable USRPs are as potential transmitters.
This is for a uni project.. I'm looking for avenues (heck you might even
say simple exercises) of aspects I can investigate for the N210 + XCVR2450.
With so much info available for the individual hardware components
Ah that makes sense!
Thanks guys!

One thing i've started to notice is that as I step up the uhd gain the

Hi All,
I've toyed around a fair bit with the UHD_sink parameters for the target
Centre Frequency, and in particular using the request command to set the
centre freq and the LO Offset.
But i can't seem to see any impact from the LO offset!
E.g.
IF = 5 MHz
Target RF = 100MHz
LO thus would equal
The XCVR 2450 covers frequencies around 2.4 GHz and 2.5 GHz and also 4.9 to
5.9 GHz.
When running uhd_usrp_probe it said 2400 to 2700MHz!
(E.g. I assume hardware performance drops off above 2.4 GHz but any reason
why it didn't cap my frequency at 2400MHz?)
..
As opposed to chopping a cosine with a vector of 1s and 0s or something...

Using existing blocks can I easily implement a formula

Hi,
I'm quite new to Linux / GNU Radio / these lists and am looking to generate
Signal Pulses.
It seems that gnuradio-radar-mono.py would be ideal for this but wasn't
installed with my GRC 3.6
nor has it been updated for a long time. According to the documentation it
