Aiming at the problem that the multi-tone interferences the satellite DSSS communication system,based on the characteristic of spread spectrum sequence and the DCT different compression characteristics of the multi-tone interference(DPI) and DSSS communication signals,the DCT part exponential distribution threshold suppression the multi-tone interference algorithm is proposed.

Based on these statistical data,we brought forward a concept of "hydrocarbon distribution threshold" ,which lays the foundation for concepts such as "probability of hydrocarbon pooling","probability of reserve distribution" and "maximum size of reservoir".

In the third chapter,we discuss the corresponding questions of locally long-tailed distributions,and then gain the corresponding results of the convolution closure of locally long-tailed distribution and locally subexponential distributions.

The effect of distributed jamming on detectability of bistatic radar is analyzed under different jamming conditions,and the results are compared with the effect of stand off jamming and stand forward jamming.

Based on the feature of integration guided adaptive antenna,the distributed jamming to the microstrip adaptive antenna array of GPS/INS guided systems is studied by the anti-jamming analysis.

This dissertation analyses advantages of distributed jamming and the characteristics of noise frequency modulation signal.
