1. A radar communication integrated cooperative detection method based on beam power distribution, which is applied to a radar communication integrated system comprising multiple pairs of radars and each pair of radars having ability to cooperatively transmit detection beams and communication beams, the method comprises:
determining a farthest detection distance and a detection volume of a single radar in a radar communication integrated system during transmitting of the detection beam when the radar has a preset transmit power;
determining a communication success probability of each pair of radars in the radar communication integrated system during transmitting of the communication beams, wherein the communication success probability represents a probability of successfully establishing a connection of communication links between a pair of radars;
determining a detection area volume of each pair of radars under different power distribution coefficients based on the farthest detection distance, the detection volume, a different power distribution coefficient of the single radar, and the communication success probability of each pair of radars, wherein the power distribution coefficient is a ratio between power distributed to the detection beam and power distributed to the communication beam;
determining a power distribution coefficient corresponding to a largest detection area volume from different detection area volumes as a current power distribution coefficient; and
determining total detection volume of the radar communication integrated system based on the detection area volume of each pair of radars and the current power distribution coefficient.
