摘要/Abstract

摘要： 提出了一种有效的频域动态压缩方法,并给出了简洁的实现形式.它能有效地抑制FMCW毫米波雷达中由射频VCO非理想性引起的泄漏三角波强干扰信号,在一定条件下,可替代AGC的复杂电路结构.

Abstract: An efficient frequency domain dynamic compression method has been developed for the anticollision system. This method, based on a frequency cancellation technique, is able to remedy the primary shortcomings of the FMCW radar-the leaked signal from the transmitter and the complex configuration of circuits. It can restrain the strong interference signal and substitute the AGC to some extent.

Key words: frequency domain dynamic compression, FMCW radar
