| titleOfInvention | Sea surface ship target imaging method and device under high sea condition |
| abstract | The invention discloses a sea surface ship target imaging method and device under a high sea condition, and relates to the technical field of airborne radar imaging. The method comprises the following steps: correcting according to the inertial navigation information pair, and converting the original echo signal into a distance-time domain; then, carrying out time-frequency transformation to convert the echo signals in the distance-time domain into the distance-time-frequency domain; carrying out radon transformation, solving the acceleration of the irregular motion of the sea surface ship target, and carrying out compensation of a high-order phase according to the acceleration; and carrying out Fourier analysis of the azimuth direction to obtain an imaging result of the sea surface ship target. The invention is suitable for airborne radar imaging, overcomes the problem of 'resolution blurring' when imaging a ship target on the sea surface under a high sea condition, realizes high-resolution imaging of the ship target, does not need to improve the hardware of the existing radar equipment, and has good engineering application prospect. |
