SETI FFTDSP Applications


Radio Astronomy & SETI

I thought a short note on using the FFTDSP program for Radio Astronomy and/or SETI would
generate some interest. The Integration feature allows increased sensitivity of the receiver by
averaging each 0.5 second FFT interval over mins or hours. If the receiving system is stable
enough, the improvement is equal to the square root of the number of averaged FFT intervals.

The SETI League has many examples of FFTDSP displays in SETI searches.
