low probability of intercept (lpi) meaning in Chinese

低拦截概率

The low probability of intercept ( lpi ) , the ability in super - resolution and anti - jamming of ultra - wide band radar challenge to the traditional receivers
超宽带雷达具有低截获性及抗侦察、抗干扰、抗摧毁等性能,对传统的侦察体制提出了巨大的挑战。
The main work of this dissertation can be summarized as follows . 1 、 the low probability of intercept ( lpi ) of uwb radar is analyzed based on the radar equation and reconnaissance equation . the necessity of making reconnaissance of uwb signal in the circumstance of low or negative snr is proved
本文主要工作如下: 1 、从超宽带雷达方程和侦察方程出发,分析了超宽带雷达信号的低截获特性,证明了超宽带雷达信号的侦察和参数估计在低信噪比条件下的必然性。
With multi - modulation , the disadvantages of single - modulation ( such as fsk , psk and ppm ) can be eliminated . by taking the advantages of different modulations , the performance of range resolving , doppler resolving and low probability of intercept ( lpi ) of the signal can be improved
复合调制信号可以克服单一信号调制形式(如fsk 、 psk 、 ppm等)的缺点,实现信号之间的取长补短,提高距离、速度分辨力,提高信号的低截获概率( lpi )性能,是雷达理论与技术的发展方向。
