Non-cellular communication radar integrated transmitting and receiving method based on vector orthogonal frequency division multiplexing

The invention discloses a non-cellular communication radar integrated receiving and transmitting method based on vector orthogonal frequency division multiplexing, and belongs to the technical field of non-cellular communication radar integration. The objective of the invention is to solve the problems that the spectrum utilization efficiency of radar target detection at present needs to be further improved and the Doppler resolution of a target is low. The method comprises the following steps of: loading data information of users to orthogonal subcarriers of V-OFDM (V-Orthogonal Frequency Division Multiplexing), carrying out power distribution on each user, obtaining a time domain signal matrix through discrete inverse Fourier transform, carrying out parallel-serial conversion, and adding a cyclic prefix; a superposed signal transmitted by an access point forms an equivalent waveform signal after passing through a pulse shaper, and the equivalent waveform signal is transmitted through an array antenna; after
