Doppler radar circuit??????

radar circuit

Hi all

Simple Doppler radar circuit

Basically is a form of transmitter and receiver which may also used as simple Doppler radar.
This is the following diagram i have for the doppler radar.

But i can not find any circuit related with my bolck diagram.

Any ideas wher i can find some info (books / web pages)


Thanks a lot

savvasn;

I'm not sure if you want weather or navigetion doppler so-

for weather try h**p://###.chmi.cz/meteo/rad/pub/wds99_dop/
(I think it was meteo or try metea)

for navigation try ###.radarpages.co.uk/theory/ap3302/ sec1/ch5/sec/ch553.htm

I found these (and more) on google
I used keywords -- doppler radar theory

I hope this helps.

thanks for your help

For theory its fine but this it will not help me to design my circuits.

I need circuits

This topic is very interesting. If No reference circuit or web can be found,
why we design one.
Which frequency band is your interested ?

doppler circuit

VCO frequiencies are typically in the 900-1500MHz range

VCO can user Delta, please ref.

Mixer can use Hittite HMC207S8, HMC208MS8 or other vendor like Minicircuits.
IF circuits is more easy to find the parts.
after IF circuits, I think a frequency counter or frequency to voltage converter is needed.
SPDT and SG, I think that is for test or calibration, so may be neglected.
