Re: RCS ????
It's not clear for me what do you exactly need, but the file in this link
http://www.mar-it.de/Radar/RCS/RCS_xx.pdf
could maybe help you. Some of its references could be useful too.
Please ask for something more specific if it doesn't help
Hi everybody!
I have a question about microstrip circulators. Looking to the data sheets of the typical providers, I'm missing information about phase stability (long term). Anyone have had experience on this issue? Is it stable the phase behaviour of the circulator in, let's say, one or two...
Hello all.
I'm looking for techniques to broad the main beam of a large phased array with uniform illumination. Due to the broadening factor is about 3, the usual quadratic phase falls in very high side lobes.
Do you know some another techniques on doing it?
Please, provide me some ideas or...
Hi, satellite.
I've been checking SONAR systems and the approach about true time delay,
interpolation, is what I was thinking to use. First a zero padding to achieve a little more time resolution and then an interpolation filter, probably a polyphase filter will be the best choice, am I right...
Re: Efficient algorithm for calculating of the small part of
Hi, Dora.
Perhaps the modified Goertzel algorithm proposed here

would suit you. I hope it. Anyway, I will continue thinking on it.
Re: Matlab
You can find at
https://www.ece.rutgers.edu/~orfanidi/ewa
an online book about MW and Antenna. It comes with a Matlab Toolbox that you can download (https://www.ece.rutgers.edu/~orfanidi/ewa/ewa.zip), with the dipole.m function you need and many things more.
Re: Hardware Configuration
What Linux distro are you planning to use? On it depends mainly hardware compatibility. When you have chosen the distro, you can select the hardware (Mandrake, for instance, has a list of supported devices).
And concerning Custom IC Design, your best choice is to use...
I'm not really sure, but I think those algorithms are aimed to DOA estimation. I have done a (not extensive) search and always found articles/references in that sense. So they could be good for tracking and for DOA interference estimator but what about a fixed beam (for example in a SAR system)...
digital subarray model
Hi, all.
This post can probably be placed at antenna forum, but I think it is a DSP matter more than a RF/MW.
I'm interested in digital beamforming for radar phased arrays. When using narrowband signals, digital beamforming can be mainly achieved by FFT processing. But...
Re: *ATTENTION: "RF" & "Antennas" to
I think they should be separated. So many ingeneers are involved in antenna development, but don't take care about the RF chain behind. Some considerations are common between antennas and RF, but many other are too much different. And with the advent of...
