| titleOfInvention | Estimation method of FDA-MIMO radar frequency deviation error |
| abstract | The invention discloses a method for estimating the frequency deviation error of an FDA-MIMO radar. The FDA-MIMO radar can distinguish echoes in different distance fuzzy regions because of the degree of freedom of the transmitting domain. When there is no carrier frequency deviation error in the transmitting array element, the The spectrum is dispersed according to the blurred regions at different distances. When there is an element carrier frequency deviation error, there will be a distance-related item in the transmitted frequency after compensation, and the clutter spectrum will be shifted and diffused. The present invention searches the power spectrum based on the clutter spectrum in the first fuzzy area, finds out the offset, estimates the size of the frequency deviation error, and avoids the increase of the clutter degree of freedom and the reduction of the clutter suppression effect of the radar system caused by it. The problem. |
