Characteristics of radar signal processing Fast Fourier Transform

Includes bibliographical references (pages 48-49)The Fast Fourier Transform is frequently used in\ud air-to-air radar applications to separate signals in\ud frequency and to improve the signal-to-noise ratio. Because\ud of its significance in these radar applications, the\ud characteristics of the FFT are critical to system\ud performance. This paper discusses significant FFT\ud characteristics and provides data examples of these\ud characteristics. The paper covers fundamental\ud characteristics such as definitions, filter size, and FFT\ud periodicity; one signal characteristics such as signal\ud position, leakage, and inphase and quadrature processing;\ud signal.in noise characteristics such as noise\ud characteristics and SNR effects; windows and window effects;\ud and two signal frequency resolution
