Principles and the electromagnetic signals detection probabilities

The detection signal principles are developed in the paper. The research aim is the creation of the mathematical modeling of the signal detection. The optical signal detection is an example. In the case the mail noise source is the day airglow. Therefore the signal detections capability depend on the noise statistics and the propagation trace as the detector parameters, inter pares crucial parameter is the signal/noise relation.

For the decision accept on the signal occurrence it is necessary first of all to record it and after that detach it from noisy signal. For this it is necessary the mathematic modeling of the detection process must be developed. The mathematical model of the process is stated in the paper. Two principles for the signal detection are declared. The first principle consist of the signal and noise are inseparable and they are simultaneous are. It is the additive principle. The second principle consist of the performance specific conditions must be performed. It is the observably principle. The probabilistic calculations are presented in the paper on the base of those two principles.
