Abstract
- The millimeter wave broadband coherent radar has the capabilities of high range resolution and Doppler resolution, which provides a new approach for anti-chaff jamming. Based on the echo model of broadband coherent radar, the range Doppler two-dimensional profile of the target is derived. Then the differences of the range Doppler two-dimensional profile between the echoes of the ship and the chaff jamming are analyzed. A range Doppler two-dimensional extended target detector based on Otsu is applied to detect the target region. Three characteristic parameters based on the range Doppler two-dimensional profile are proposed to discriminate the ship and the chaff jamming. An identification method based on those characteristic parameters is presented to discriminate the chaff jamming and the ship. Experiments with measured data validate the effectiveness of the identification method via range Doppler two-dimensional profile.
