Abstract:The FFT summation detector is a technique that has been widely used in civilian spectrum monitoring and military radio surveillance for detecting narrowband signals in noise. In practical implementations of the FFT summation detector, the detection threshold is set as the product of the channel noise power, which is often adaptively estimated from the FFT filter bank output, and the normalized detection threshold T n , which is usually computed by solving a nonlinear equation.
