What is main objective of signal detection?
The goal of signal detection theory is to estimate two main parameters from the experimental data. The first parameter, called d′, indicates the strength of the signal (relative to the noise).
How do we detect the signals?
With an LTC1164-8, signal detection is accomplished by selecting a very narrow signal detection band around the frequency of the desired signal, which is defined as fCLK divided by 100 (fCLK is the clock frequency of the LTC1164-8), and by selecting the filter gain by choosing the value of a resistor.
What is probability of detection in radar?
Wanted signals shall, on the one hand, reach the indication as of a minimal amplitude, on the other hand, the false alarm rate may not increase. probability of detection PD is the ratio of detected aims to the number of all possible blips on the radar screen, i.e. all possible targets in a given direction. PD =
How probability of detection affects probability of false alarm in radar?
For all faults of the system, it is assumed that the probability of miss detection is fixed to 0.02 and the probability of false alarms is fixed to 0.05.
