how can i detect a target with MATLAB code using two signals( one is direct path FM signal and another one from moving target(aerial target) echo+noise) please help me in this regard.

i want to detect the target using FM broadcast signals( ie., two different signals one is directly received from transmitter and second signal is received from target(echo+noise) can anybody suggest me the what type of algorithms i can use, if possible please send me the matlab code.

Thank you,
