Adaptive nulling in monopulse difference antenna diagram to improve the angular resolution at object locations

摘要

The method involves synchronously emitting separate radar beam lobes covering an angular scanning range by radar sensor (12). The target responses corresponding to the emitted radar beam lobes are received by the sensor as measured values. The target responses are superimposed arithmetically to generate a synthetic radar beam lobe having a zero value in the scanning range. Independent claims are also included for the following: (1) collision avoidance assistance provision method; (2) computer-readable medium storing obstacle detection control program; and (3) driver assistance system.
