SIGNAL PROCESSING METHOD, AND APPARATUS

A signal processing method, and an apparatus. The method can be applied to the technical field of detection. The method comprises: controlling a detection apparatus to transmit a detection signal, the detection signal comprising a plurality of bursts (S310); determining the stepping bandwidth of the detection signal (S320); and, according to the stepping bandwidth, determining an extreme value comparison mode for a unit to be detected, said unit belonging to a first spectrogram obtained by performing spectrum analysis on a return signal of the detection signal. The method can be applied to intelligent vehicles or new energy vehicles, and can avoid inaccurate extreme value comparison results due to detection signals relating to stepping, improving the capabilities of target contour estimation and classification and recognition. L'invention concerne un procédé de traitement de signal et un appareil. Le procédé peut être appliqué au domaine technique de la détection. Le procédé consiste à : commander un appareil
