Abstract: | A monopulse angle measurement method for polarization array radar is studied in this paper. The receiving signal model is established and then a monopulse angle measurement method based on virtual polarization matching is proposed. To analyze the estimation performance, the Cramer-Rao Lower Bound (CRLB) of angle estimation is derived. Both theoretical analysis and simulation show that: firstly, the proposed method is superior to the traditional angle measurement methods based on the single polarization. Secondly, the performance of the new method is unrelated to the echo polarization. Thirdly, angle estimation of this method is asymptotically optimal. The results show that this method has great potential to be used in polarization array radar. |
