A radar system sends out a specific signal to detect objects in the environment. The received signal is noisy, and the system uses a matched filter to identify objects by maximizing the signal-to-noise ratio.
What is the primary purpose of using a matched filter in radar systems?

Correct option is B

​$$\text{A matched filter is designed to be matched to the known transmitted signal waveform. Its key property is that it maximizes the output signal-to-noise ratio (SNR) at a specific sampling instant when the received signal is corrupted by additive white noise.} \\[10pt]\text{This makes matched filters ideal for:} \\[6pt]\bullet \ \text{Radar target detection} \\[4pt]\bullet \ \text{Communication receivers} \\[4pt]\bullet \ \text{Extracting weak signals from noise}$$​​
