Method for operating a MIMO radar

摘要

In a method for operating a MIMO radar, an influence of an object motion on an angle estimate is substantially eliminated, and a time multiplex schema having a transmission sequence and transmission instants of transmitters of the MIMO radar is identified by optimizing the following mathematical relationship:;d_pulses,opt=arg⁢⁢maxd_pulses⁢[VarS⁡(d_pulses)-(CovS⁡(d_pulses,t))2/VarS⁡(t_)]
in which: dpulses,opt is optimized positions of the transmitters in the sequence in which they transmit; dpulses is positions of the transmitters in the sequence in which they transmit; t is transmission instants; VarS is sample variance; and CovS is sample covariance.

1. A method for operating a MIMO radar such that an influence of an object motion on an angle estimate is substantially eliminated, the method comprising:
identifying a time multiplex schema having a transmission sequence and transmission instants of transmitters of the MIMO radar by optimizing the following mathematical relationship:d_pulses,opt=arg⁢⁢max⁡[VarS⁡(d_pulses)-(CovS⁡(d_pulses,t))2/VarS⁡(t_)]d_pulses wherein: dpulses,opt is optimized positions of the transmitters in a sequence in which the transmitters transmit; dpulses is positions of the transmitters in a sequence in which the transmitters transmit; t is transmission instants; VarS is sample variance; and CovS is sample covariance.
