Abstract
The pulse center detector (PCD) produces an amplitude-independent center-triggered range output for precision radar rangefinders and TDR systems. Pulse center triggering is accomplished by triggering leading-edge and trailing-edge detectors and summing the outputs to produce a computed center-triggered result. Since the occurrence time of a pulse center does not vary with amplitude, the PCD is amplitude-independent. The PCD overcomes limitations of prior automatic pulse detectors, such as the inherent latency of a constant fraction discriminator (CFD) and the uncertainty of a time-of-peak (TOP) detector. The PCD can be implemented with a single analog component—a comparator—and thus requires appreciably fewer analog components than prior automatic detectors while providing lower jitter. Applications include radar and TDR tank gauges, and radar rangefinders for robotics and automotive applications.
