Radar circuit for recognition of moving objects - uses charge coupled integrated semiconductor circuitry for comparison of echo signals

摘要

The radar technology for the recognition of moving objects makes use of two charge transfer circuits (A,B), to produce a common output signal, whereby, the first echo signal received after being emitted by the transmitter is fed via a computing point (10) to the information input of one charge transfer circuit (A), and the second echo signal is treated likewise and fed to the information input of the other charge transfer circuit (B). An inversion of the stored information in one of these circuits is provided for. Thus, to produce an output signal, the two pieces of stored information due to the first and second pulses are combined, the coupled charge transfer circuits (A,B) forming a comparator for the two echo signals received from the moving object.
