Hi everyone!
i want to make a doppler radar circuit to measure vital signals on 5,8GHz. someone make it before and i will try to lengthen the distance, ie they get the vital sign from 3 meters in 90% accuracy and i will try 5 meters in the same accuracy. i found a circuit on scholar google. i will buy the all components part by part (ie vco , PA...) but i am not sure what the exact components are.
i found : VCO, LO Driver, PA, mixer, sma connector,resistor,capacitor, board. i think i must get these. And what should i buy another?
i do't need circulator because i will use patch antenna for both Rx and Tx. After i make the circuit i will process the signal by Matlab. In Matlab i will use BPF(band pass filter) so i don't need a BPF circuit.
Also what is the IF block on this board?
is it a block that i can buy?
So many thanks for your helps.
