中文摘要：
多点定位是空中交通管制的新兴技术，抗干扰技术是多点定位系统走向实用的关键。针对多个目标发射信号的混叠问题，在分析A/C模式混叠信号时域特征和规律的基础上，定义了脉冲重叠度和脉冲描述字，并将混叠信号的分离归结为其子脉冲的分离和归位。再根据混叠子脉冲的脉宽、幅度、相位等特征，提出了混叠子脉冲的分离方法，进而实现了整个A／C模式脉冲串的解混叠。仿真验证了算法的有效性。
英文摘要：
Multilateration is a new technology in air traffic control. Anti-jamming technology is important for multilateration systems. Signals for different targets will generate garbles which are main jamming in multilateration. This paper analyzes the features and laws of A/C garbles in time domain, defines pulse aliasing degree and pulse description words, and proposes a new algorithm to separate the aliasing pulses in time domain according to pulse width, amplitude and phase. The A/C transponders are separated totally after sub-pulses are cleared. At last, simulations show the efficiency of proposed algorithm.
