摘　　要：提出一种基于"半周期峰值比法"的周期识别新技术,它是全数字化的,不需使用任何附加的模拟电路和硬件支持。新技术是基于每个罗兰C脉冲的采样点数的,因此在有噪声的情况下,增加识别过程的可靠性。A new technique is presented in this paper. It is based on the widely used analogue "half-cycle peak ratio" technique, form which it differs by being entirely digital, no additional analogue signal processing or other hardware is required. The new method makes decisions based on a large number of sample points in each Loran-C pulse, thereby increasing the resilience of the identification process in the presence of noise.
