Method and devices for determining the distance of an object by evaluating the signals of an amplitude-modulated CW radar |
摘要 |
In this method it is proposed to key two rectifiers (KG1, KG2) followed by a low-pass filter (TP1, TP2), directly and shifted by 90 DEG with the modulation signal and to determine distance ranges or distances. Alternatively, the range of unambiguousness can be divided into n + 1 distance ranges by means of digital computers. The distance ranges are evaluated by means of n voltage comparators (K) followed by a logic device. A construction with n = 1 is particularly simple in this arrangement. <IMAGE>
