A New LFM-Signal Detector Based on Fractional Fourier Transform
<p/> <p>A new LFM-signal detector formulated by the integration of the 4th-power modulus of the fractional Fourier transform is proposed. It has similar performance to the modulus square detector of Radon-ambiguity transform because of the equivalence relationship between them. But the n...

But the new detector has much lower computational complexity in the case that the number of the searching angles is far less than the length of the signal. Moreover, it is proved that the new detector can be generalized to the integration of the <it>n</it>th-power (<inline-formula> <graphic file="1687-6180-2010-876282-i1.gif"/></inline-formula>) modulus of the fractional Fourier transform via mathematical derivation.
