Abstract
A weak target detection method includes transmitting a plurality of frequency modulated continuous wave signals during rotation of a microwave radar sensor, receiving a plurality of echo signals reflected by a weak target, accumulating the plurality of echo signals in a beam width of the microwave radar sensor to obtain an accumulated echo signal, and determining position information of the weak target according to the accumulated echo signal.
