摘要：
A transmitter employing a cryptographic algorithm and key generates and transmits a staggered pulse signal that includes a plurality of high-power pulses that are part of a pseudonoise (PN) code. The high-power pulses are separated by a group of low-power chips and the time interval between the high-power pulses is varied according to the cryptographic algorithm and key. A receiver, employing a corresponding cryptographic algorithm and key receives the signal and correlates it with a locally generated code that is modified according to the cryptographic algorithm and key to detect the phase of the received PN code. The receiver also can include a matched filter configured according to the cryptographic algorithm and key to detect the sequence of high-power pulses in the received signal.

使用加密算法和密钥的发射机产生并发送包括作为伪噪声（PN）码的一部分的多个高功率脉冲的交错脉冲信号。 高功率脉冲由一组低功率芯片分离，大功率脉冲之间的时间间隔根据密码算法和密钥而变化。 采用相应的加密算法和密钥的接收机接收信号并将其与根据密码算法和密钥进行修改的本地生成的代码相关联，以检测接收到的PN码的相位。 接收机还可以包括根据加密算法和密钥配置的匹配滤波器，以检测接收信号中的高功率脉冲序列。
