An electronic warfare (EW) receiver based on fast Fourier transforms (FFTs) with different frame sizes is presented. With a given sampling frequency, an FFT-based EW receiver can improve its frequency estimation by increasing the FFT frame size; however, such an increase has detrimental effects on its time-of-arrival and pulse width estimations. By applying multiple FFTs with different frame sizes, the proposed EW receiver can achieve high time and frequency resolutions simultaneously.
