Abstract :
In this paper, a new detector based on the origin moment of fractional spectrum (OMFrS) for LFM signal is proposed. The fourth order OMFrS is established as a detector for LFM signal via the proof of the equivalence between the fourth order OMFrS and the modulus square detector of RAT. Then the detector is generalized to arbitrarily high-order OMFrS via mathematical derivation. The simulation results show the good performance of the new detector.
