Radar system for monitoring targets in different distance ranges

摘要

Radar system for monitoring targets in different distance ranges with the following measures: - Radar pulses are transmitted whose length is greater than the transit time between two objects to be separated at different distances or distance ranges The high-frequency signal and the radar received signal are fed to a mixer (6), - the output signal of the mixer (6) is fed to a signal evaluation unit (9) via at least one scanner (7, 8) whose delay setting in relation to the rising edge of the radar transmission pulse defines the range limit of the distance range to be monitored ; a direct connection (11) being provided in parallel to the at least one scanner (7, 8) between mixer (6) and signal evaluation (9).
