| Abstract: | This paper describes a superheterodyne sliding window FFT electromagnetic environment monitoring system controlled by a computer,the principle of its work and the design of software and hardware have been analyzed briefly. It can determine the electromagnetic spectral odcupancy in 3-30MHz or in some interested bands of them,it also can measure the background level of atmospheric noise. |
