What is the minimum signal voltage that can be reliably detected?

For voice signals the required SNR might be as low as 6 dB and for CW (Morse) it might extend, with a trained listener, down to 1 dB difference (tangential sensitivity). Usable in this context then means it conveys adequate information for decoding by a person or a machine with acceptable and defined levels of error.

What is minimum detectable signal in radar?

The Minimum detectable signal (MDS) is the minimum power level that can be processed by a receiver to provide a relevant output. It is also known as the noise floor of the system. It can also be defined as the input signal power required to give a particular SNR at the output.
