Embodiment 1
[0062] See figure 1 , figure 1 It is a schematic flowchart of a frequency diversity MIMO radar parameter estimation method based on the matrix beam principle provided by an embodiment of the present invention. An embodiment of the present invention provides a method for estimating parameters of a frequency diversity MIMO radar based on the principle of matrix beams. The method for estimating parameters of a frequency diversity MIMO radar includes steps 1 to 8, wherein:
[0063] Step 1. M transmitting array elements transmit orthogonal signals.
[0064] In the embodiment of the present invention, the monostatic signal model of the frequency diversity MIMO radar is considered, such as figure 2 As shown, the transmitting end adopts M transmitting array elements, and the arrangement of the array elements adopts a uniform linear array structure, and the distance between the array elements is d t . The receiving end adopts N receiving array elements, and the arrangement of the ...
