The invention provides a method for calculating a moving
target angle of a time division multiplexed
MIMO radar. According to
specific time division
multiplexing time sequences of a transmitting
antenna array element and a receiving
antenna array element, a
virtual antenna array obtains all rounds of receiving signals according a first
array element, a second
array element, a third
array element,a fourth array element, ..., and an MNth array element; and each round of receiving
signal obtained by the
virtual antenna array is processed as follows: step a, distance direction
processing is carried out to obtain a distance direction
signal; step b, first digital beam forming
processing is carried out, a virtual beam array in which a target is located is extracted by a target detection methodand is synthesized with the distance direction
signal, and the target speed is calculated; step c,
phase compensation is carried out on the distance directions signal of the target; and step four, second digital beam forming
processing is carried out and then a correct angle of the target is calculated. According to the invention, no redundant
virtual array element needs to be designed and angle calculation of the low-signal-to-
noise-ratio target is realized.
