摘　　要：提出一种对复杂波形核脉冲信号进行梯形成形的方法。该方法将复杂波形核脉冲信号看成传递函数的冲激响应,对传递函数因式分解成一阶惯性环节和的形式。采用粒子群算法对复杂波形核脉冲信号进行识别,得到一阶惯性环节的个数、各个环节的比例系数以及脉冲幅值相关系数、发生时间和时间常数等参数。通过所识别的参数进行其梯形成形的公式推导及仿真实验表明,该方法获取的脉冲幅值精度较高。A trapezoidal forming method for complex waveform core pulse signal is presented.In this method,the complex waveform core pulse signal is regarded as the impulse response of the transfer function,and the transfer function is factored into the form of the first order inertia link sum.The complex waveform core pulse signal is identified by particle swarm optimization(PSO),and the number of first-order inertia links,the proportional coefficients of each link,the amplitude correlation coefficient,the occurrence time and the time constant are obtained.The formula of trapezoidal forming is derived by the identified parameters and the simulation experiment shows that the pulse amplitude obtained by this method is of high precision.
