To obtain an accurate polarization scattering matrix, simultaneous full polarization radar
systems must transmit two signals. The performance of orthogonal polyphase codes
designed by the traditional method is limited by the code length and is sensitive to Doppler
frequency. In this paper, we propose a design method for orthogonal polyphase codes that
have good Doppler tolerance. We consider the peak sidelobe level and isolation and
transform the signal design problem into a nonlinear optimization problem, which we solve …
