| titleOfInvention | A low-altitude target altimetry method for meter-wave TR MIMO radar based on sparse array |
| abstract | The invention discloses a sparse array-based metric-wave TR MIMO radar low-altitude target altimetry method, which is characterized by comprising the following steps: S1. Constructing a monostatic metric-wave sparse array TR MIMO radar system, respectively calculating and obtaining the transmit direct wave guide vector at (θ d ) and reflected wave steering vector at (θ s ) ; S2, construct composite steering vector A(θ); S3, calculate received data Y, construct data covariance matrix R, and compare data covariance matrix R Perform real-value processing with the composite steering vector A(θ) respectively to obtain a real covariance matrix R U and a real-valued composite steering vector A U (θ); S4. According to the composite steering vector A(θ) and the data covariance matrix R or Real covariance matrix R U and real-valued composite steering vector A U (θ), use generalized MUSIC algorithm and maximum likelihood algorithm to search for spectral peaks, observe and obtain spatial spectrum, find out the angle corresponding to the position of the wave peak, that is, obtain the target Low Elevation Estimates S5. Estimated value of the obtained low elevation angle of the target After conversion, the target height data H is obtained. |
