x band doppler module
Hi experts i will appreciate any help and idea about decision to design a K-Band doppler patch antenna.
What i exactly want to design and build is a motion detector which uses doppler shift technigue. It has to detect motion and speed and then if i can achieve these i can try for detecting direction. As i did some search on google i learned that i need two outputs from antenna module which are 90 degree shifted and compare them to sense the direction of the movement. this link shows what i exactly want to build like,
**broken link removed**
i know theese are X band but i will try for K Band.
Now let me tell you what i know and dont know about antennas so you can show me a way where to start. First i dont know what must be the routing thechnique of the patch antenna on pcb. i think i have to transmit a 24.125 Ghz wave at a power in terms of dB which is approprite to the standards of my country. and then receive it back. then produce an intermediate frequency and then amplify it in order to compute it with a microcontroller to sense speed and motion. also will i need to use a horn?
Please help me about its feasibility and where to start, do you have any recommended readings.
Thanks for any help.
