Title:
RADAR ANGLE AND DISTANCE ESTIMATION METHOD BASED ON TENSOR HIGHER-ORDER SINGULAR VALUE DECOMPOSITION
Document Type and Number:
WIPO Patent Application WO/2022/127076
Kind Code:
A1
Abstract:
Provided by the present invention is a radar angle and distance estimation method based on tensor higher-order singular value decomposition, comprising the following steps: constructing a multiple-input multiple-output (MIMO) radar reception array containing k subarrays, obtaining received data of a target echo by means of said MIMO radar reception array, and constructing a third-order tensor signal model; using a higher-order singular value decomposition third-order tensor signal model, obtaining a tensor-based signal subspace; extracting a reception matrix of said signal subspace to achieve estimation of direction of arrival (DOA) parameters for a MIMO radar target; the signal subspace and transmission matrix corresponding to each subarray is extracted and the phase ambiguity problem caused by the coupling of target direction of departure (DOD) parameters and distance is eliminated, while automatic matching of target DOD and distance with DOA parameters is also achieved, ultimately enabling estimation of DOD parameters and distance parameters of a MIMO radar target.
