Quick detection method for high-frequency sky wave radar of moving object at sea

The invention discloses a quick detection method for a high-frequency sky wave radar of a moving object at sea, and the method comprises the following steps: building a monitoring threshold G; searching all distance units passing through the detection threshold G, and passing the step 1; judging whether the distance units at step 1 are adjacent to each other or not; passing the step 2 if the distance units are isolated; determining whether the isolated distance units passing the step 2 are located at positive and negative Bragg peaks or at a position of '0 Doppler frequency ' or not; passing the step 3 if the isolated distance units passing the step 2 are not located at positive and negative Bragg peaks or at the position of '0 Doppler frequency ', and determining that there is the moving object within a distance threshold. The method can effectively reduce the echo broadening and ghost caused by ionized layer pollution, eliminates all false alarms, and can detect any one moving object quickly.
