What do you mean by minimum detectable signal?
A minimum detectable signal is a signal at the input of a system whose power allows it to be detected over the background electronic noise of the detector system. It can alternately be defined as a signal that produces a signal-to-noise ratio of a given value m at the output.
How does the sonar equation inform sonar engineering?
The equation computes the received signal-to-noise ratio (SNR) from the transmitted signal level, taking into account transmission loss, noise level, sensor directivity, and target strength. The sonar equation serves the same purpose in sonar as the radar equation does in radar.
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.
What is the sonar equation?
The “sonar equation” is a systematic way of estimating the expected signal-to-noise ratios for sonar (SOund Navigation And Ranging) systems. The signal-to-noise ratio determines whether or not a sonar will be able to detect a signal in the presence of background noise in the ocean.
