Algorithms depend on what is your passive radar configuration. Do you have directional antennas or omni-directional? How many antennas your system has? Are are the channels synchronous, i.e., the phase difference is small? The target modeling step can be initially seen from the literature discussing bi-static radars.

thank you very much with your suggestions i got clear idea, now i am working on FM

based passive radar,where i am using omni-directional antennas, and my system

configuration is one FM transmitter, two receiving antennas one is for direct signal

from tx another for echo signal reflected from target, initially i considered stationary

target later i'll try for moving target.  till now i was modeled and calculated of the

received signal delay at receiver. 

now my problem is:

how can i calculate the position of the (stationary) target initially in 2D and later in

3D,with known bi-static range(ie., tx to target to rx, ), DoA , AoA

please help me....([email protected])

thanking you sir

Can you tell me what is your objective? Based on what assumption are you considering FM, why not DVB-T or AM or GSM? why did u choose one transmit and two receive antennas. Why do you think one antenna will catch only signal from transmitter while other only echo (in reality both antennas will catch transmit signal and echo)?  

Sorry for not answering directly, but I want you to have rationale behind all your decisions. Let us continue discussion on this thread.  

thank you for your replay, here my obective is to study and simulate the FM based passive bi-static radar. yes as per your replay and my survey i considered only one antenna at the receiver to receive both the signals and processed using matched filter.  by assuming some bistatic range i got the target range...

now my next problem is to locate the target using these values that is Rr,Rt, and R(Rr+Rt=R=bistatic range) with some angel theta...

let me know how can i find the two dimensional location(x,y) with known transmitter and receiver positions, separated some distance

Hello!

Are you still working on passive radar signal processing? I am intrested in doing research in DVB-T based systems.

Hello tamas peto, ya i am working on passive bistatic radar signal processing

Hi there .I am doing thesis in passive bistatic radar in master university. I suggest you to simulate by do the model of it .The model should be coherent receiver such as usrp b210 then pass to adaptive noise cancellation final is cross correlation for comparing time difference.

Thank you Tom Chun,

can you please share your email id,

and do you have any real Data, if yes please share,

thank you
