Based on the practical planar detection area considering various influence of environment factors synthetically,it is a problem to be discussed deeply to establish models of practical detection probability distribution of radar network.

The variations and probability distributions of these parameters versus solution treatment time were also studied.

This paper presents a method which adopts direct processing and computing of the spot image to obtain the laser spot drift and its probability distribution.

It sets up mathematical model of impact point prediction simulation statistics and can estimate probability density distribution matrix of missile impact piont and effectively improves estimated accuracy of missile dropping area.

Establishing its mathematical model requires the prediction of its probability density distribution.

Overall description of MAN traffic was presented and law in traffic aggregate process was illstrated with probability density distribution method based on analysis of a good number of traffic data sets collected straightly from different sources and backbone links on Xi an broadband multimedia network.

Statistical Measurement Method of Radio Disturbance——Amplitude Probability Distribution( APD);

Amplitude Probability Distribution (APD) has been proposed within CISPR as a measure of the emitted electromagnetic energy from electrical equipment.
