摘　　要：测距询问器通过计算询问脉冲和应答脉冲之间时间差的方法来获得距离信息。应答脉冲经过地面发射机发射后,经过空间干扰、接收通道噪声和非线性等作用后,接收到的应答脉冲波形已发生畸变,甚至不可认识。在无法改变信道特性的条件下,基于从畸变信号中提高信号可用性的角度出发,本文介绍测距系统的组成与原理,并建立了一种畸变准高斯波形的分析处理方法,为测距询问器的设计做出参考。The airborne distance measure interrogator obtains the distance information by the method of calculating the timebetween the interrogation pulse and the response pulse. After transmitted by the ground transmitter, the receiving response pulse isdistorted through the influence of the space interference, the channel noise and the nonlinear. In the case of the channelcharacteristics cannot be changed, the composition and working principle of the distance measure system are introduced in this paperbased on improving the availability of the signal. An analysis processing method of distorted quasi-gauss waveform is establishedand the reference for the design of airborne distance measure interrogator is given.
