Abstract
A method and a device for direction of arrival estimation based on one-bit quantization antenna array, the method including: designing a received signal model of robust one-bit radar, designing an optimal objective function of the robust one-bit radar, replacing a first function in the optimal objective function with a second objective function to obtain a new optimal objective function, and according to the new optimal objective function, adopting a proximal alternating minimization method and a gradient descent method to solve the optimization problem and obtain an incident angle of a target echo signal. The embodiments reshape the received signal model of the one-bit radar, enabling the received signals to preserve or reflect the distribution information of noise data. The embodiments utilize a specific norm to describe the distribution of noise, effectively suppressing quantization error bits generated by low signal-to-noise ratio when estimating DoA with one-bit algorithm.
