+    echo_processing_MF( echo_mtx, PRF, fs, fc, B, D, d, sigma_n, P_fa )
+% This function processes echo data using matching filter method.
+%
+% Usage: 
+% [echo_rd_mtx, target_list_RDA, sigma_n_rd] = echo_processing_MF(echo_mtx, PRF, fs, fc, B, D, d, sigma_n, P_fa)
+% Inputs:
+%   echo_mtx:       Matrix containing the echo data
+%   PRF:            Pulse Repetition Frequency
+%   fs:             Sampling frequency
+%   fc:             Carrier frequency
+%   B:              Bandwidth
+%   D:              Duty ratio
+%   d:              Antenna spacing
+%   sigma_n:        Input noise level of the echo data
+%   P_fa:           False alarm probability threshold
+%
+% Outputs:
+%   echo_rd_mtx:        Echo matrix after range-Doppler processing
+%   target_list_RDA:    List of detected targets
+%   sigma_n_rd:         Estimated noise level after range-Doppler processing
