本文提出一种频率定义的游标数字-时间转换器(DTC)，用于脉冲雷达系统。该DTC利用频率定义方法实现高精度时间分辨率，解决了传统DTC在脉冲雷达中分辨率和范围折中的问题。
multi-path immunity for ranging and localization applications [1], [2]. Impulse radar sends signals with short duration and spreads signal power over a large bandwidth. Favorable features of impulse radar are minor interference with other wireless systems as well as high immunity to nearby radio signals. Thus, impulse radars are compatible with the harsh environments where intensive radio services are operating. In conjunction with the advantages of high integration and low cost in mass production from CMOS technology, more ubiquitous utilizations are feasible for CMOS impulse radars. In impulse radar, the distance between the radar system and an object can be extracted from the flight time of pulses. A straightforward way to measure the timing difference between these pulses with fine resolution is by using time-todigital converters (
