I have a horn antenna (centered at 2.4 GHz). It was used previously by the group who made the first prototype.
What do you suggest about buying broadband oscillator ICs, amplifying their signal and feeding it direct to the antenna?
Sir, my task is to 'design' the radar, not buy it. Of course making oscillators is like re-inventing the wheel.
If you were me, how would you design a continuous wave transmitter?
I appreciate your concern about the radio astronomers. What do you suggest I should do?
Yes, my radar will distinguish emitted pulse from its echo relying on time. Luckily today, we had some good results with Step Recovery Diode (SRD). Pulse durations were < 1ns in simulations, of course. And...
I apologize for this gaping hole in my conversation. I should've explained them. Thank you for pointing it out.

Hey Enthalpy, how are you doing? Thank you for replying.
I think you missed the most important part of my post: I am quite an amateur in microwave electronics and where I am studying, this project is first of its kind. I am an UNDERGRAD as well. :)
I am grateful to you for providing so many...
Hello all,
Its Ali here. I am a Electrical (Telecom) Engineering student and my Final Year Project (FYP) is Portable GPR in which I am designing UWB transceiver. Currently I am working on the transmitter part.
Here are a few specs of the design:
-Simulation Software: NI Multisim 12.0.1...
@ Bobbywhy
First of all, Thank you for replying.
Secondly, I stated that I have to develop a system (transceiver) which can remove the use of VNA in already-developed project. :) I know there are various expensive but handheld VNAs are available in the market. They are of no use to me as I can...
@ skeptic2
These are the questions I would consider if I knew where to begin with and that is why I posted here to get a head start. :) But no luck till now. ;(
Yes, I'll only be replacing the VNA (refer to my second reply to this post). Rest of the things like antenna, algorithms will remain...
Is there anything else you can suggest?
let me show you a block diagram. Its of a UWB transceiver. But I think it would be too expensive to make and time duration is just 1 year. If there is a cheaper alternative, I would love to hear it. It needs not be state-of-the-art. Schematics will be...
Hello Bobbywhy,
I have a collection of a lot of research papers and theses. All of them do not have schematics. They have block diagrams only and me being a BEE student, find them not helping enough. I hope upto 20 google search result pages are enough. :)
In addition to it...
Does anybody know how to design a UWB Stepped-Frequency Continuoud Wave (SFCW) or Frequency Modulated Continuous Wave (FMCW) Transceiver?
If you have schematics or you can explain a relevant block diagram in detail, please reply.
Regards,
Ali

S11 (11 is in subscript) = First parameter of S-Matrix. In Electromagnetism, it is simply the reception of what you are sending in the form of waves.
I hope I did not miss anything.
Hello,
I am a final year student of BEE Telecom. I chose my Final Year Project to design a Transmitter and Receiver for GPR. GPR has already been developed in my institute. It uses VNA as its source. Since VNA is a multipurpose device and the already-implemented project used it to find S11...
@ Jiggy-Ninja
With due respect, what do you mean by 'equivalent of an associate degree'? :) I am not taking it personally as in my region, associate engineers are Diploma holders where as I am doing Bachelors in Electrical Engineering (BEE). There is quite a difference between both.
I infer...
