Abstract

Objectives Phased array radar is difficult to ensure the static alignment of electric axis, therefore a research into dynamic alignment method is conducted.
Methods With the real-time measurement of the ship's attitude and position information and the signal source position information, the real-time target true value and detection value of the phased array radar are obtained through attitude and position correction algorithms with a unified time reference. Then, the zero error of the electric axis of the phased array radar is obtained, thus achieving dynamic alignment.
Results The simulation results show that the accuracy of the alignment method can reach about 0.5'.
Conclusions This method meets the alignment requirements of phased array radar, reduces the requirement and saves the test cost, and has strong flexibility and mobility.
- phased array radar,
- electric axis,
