77 GHz millimeter wave array antenna with two transmitters and four receivers and algorithm thereof

The invention discloses a 77 GHz millimeter wave array antenna with two transmitting and four receiving and an algorithm thereof. The 77 GHz millimeter wave array antenna comprises a close-range transmitting antenna, a long-range transmitting antenna, a close-range receiving antenna and a long-range receiving antenna. The 77 GHz millimeter wave array antenna is characterized in that the signal input end of the close-range transmitting antenna is connected to the signal output end of a close-range transmitting branch; the algorithm comprises the following steps that a linear frequency modulation continuous wave signal is generated through a waveform generator and is modulated into a 77 GHz millimeter wave radio frequency band; and a time linear frequency modulation continuous wave signal isradiated into space through a waveform generator transmitting antenna to become an electromagnetic wave signal propagating in space, when the electromagnetic wave signal meets an object.
