The invention provides a distributed
radar angle
estimation method and device, and the method comprises the steps: obtaining more than two
radar signals, and carrying out the independent
processing of the
radar signals, and obtaining corresponding first data; acquiring all first data, and performing association
processing in a centralized manner to obtain second data; estimating the angle of each radar based on the second data to obtain a corresponding initial angle
estimation value; and constructing a distributed radar observation model based on the second data and all the initial angle
estimation values, and performing iterative
processing to obtain a final angle estimation value. Based on a target-driven self-calibration mechanism, high-precision angle estimation of a distributed radar
system is realized without precise time and
phase synchronization, high-precision time and
phase synchronization of a plurality of radar nodes is not needed, and the method does not depend on additional synchronization hardware or a complex calibration process. And
phase alignment among the radar nodes can be realized only through an
algorithm, so that the design complexity and cost of the
system are remarkably reduced, and the
engineering realizability is improved.
