Radar Emitter Signal Sorting Based on Pulse Phase Linearity

In order to solve the problem of signal sortinglead-alarm and improve the accuracy of signal sorting, a new radar emitter signal sorting algorithm based on the pulse phase linearity is proposed. The process of pulse phase linearity detection is discussed and verified by simulation. The main principle of the proposed work is sorting characteristic parameteris extracted. Then the steps of signal sorting algo- rithm are given. Simulation experiment has been carried out, which shows that the algorithm can be ap- plied into radar emitter signal sorting under low input signal-to-noise ratio. Obviously, the algorithm will have a bright future in the field of ELINT.
