摘要

在MTI或脉冲多普勒雷达中使用的模数转换器(adc)由于其非线性，会产生大量杂波回波的杂散信号。在雷达的多普勒通带中，这些伪信号可以表现为真实的移动目标。本文从数学上说明了如何减轻这些杂散信号，并提供了实现该过程的方法。

ADC spurious signal mitigation in radar by modifying the LO

Analog-to-digital converters (ADCs) used in MTI or pulse Doppler radars generate spurious signals from large clutter echoes because of the non-linear ADCs. These spurious signals can appear as real moving targets in the Doppler passband of a radar. The paper shows mathematically how these spurious signals are mitigated and a means of implementing the process is provided.
