| Abstract: | Taking biphase code signal and quadrature phase code signal as an example, this paper proposes an algorithm to achieve an extraction of the intrapulse modulation characteristic of the phase-coded radar signal under the condition of low signal-to-noise ratio. Simulations, experiments result in laboratory and external field are carried out to demonstrate the effectiveness of the proposed algorithm. |
