Embodiment Construction
[0033] Aiming at the problem of deterioration of positioning accuracy of traditional methods in the case of short baselines, the present invention proposes a high-precision positioning method for broadband radar targets based on phase estimation distance and phase estimation angle. The invention will be described in detail below in conjunction with the accompanying drawings.
[0034] The inventive method is realized by the following technical solutions, and the realization flow chart is as follows figure 1 Shown:
[0035] Using the antenna configuration of single transmission and multi-reception, the transmitting antenna transmits RF broadband waveforms, and multiple receiving antennas receive echoes at the same time, and the transmitting antenna and each receiving antenna channel form a transceiver channel. Denote c as the speed of light, f c is the center frequency of the transmitted signal, B is the bandwidth of the transmitted signal, T is the frame length of the transmit...
