METHOD FOR SELECTION OF SIGNALS FROM OBJECTS CLOSING WITH MOTOR VEHICLE AND DEVICE FOR ITS REALIZATION Russian patent published in 1997 - IPC

FIELD: radio engineering. SUBSTANCE: invention is intended for use in gears preventing collision of motor vehicles. It consists of selection of signals from objects (called dangerous) for meeting with which there remains time t_b determined beforehand. This is achieved with the use of signal selection from dangerous object in each range interval (in each range selector) by means of corresponding selection of signals from dangerous objects, i.e. by suppression of signals from all objects except those which closing speed (Doppler frequency range) is determined by range of distance for which selector is set and specified time to meeting with subsequent transmission of selected signals for processing in OR circuit. EFFECT: improved reliability and increased functional efficiency of the device. 3 dwg
