Matched Filter for FMCW radar?

How can I perform a matched filter for FMCW radar? I can only find information about pulsed waveforms. I'm using a FMCW radar and the signal is to noisy, so I have to find a solution to increase the SNR. The FMCW radar uses a uniform rectangular array of 2x2 elements

In general, matched filter is defined as the conjugated reversed waveform and that definition applies to FMCW waveform too. However, in reality, FMCW waveform often achieves the same by mixing the received signal with the transmitted signal, as what happens in dechirp() function.
