The method comprises the following steps: step 1, preprocessing a training picture in a text data set; step 2, establishing a PSENet progressive scale growth network, and finishing feature extraction, feature fusion and segmentation prediction on the training picture by utilizing the progressive scale growth network to obtain segmentation results of a plurality of prediction scales; step 3, carrying out supervised training on the PSENet progressive scale growth network established in the step 2 to obtain a detector model; step 4, detecting the to-be-detected picture; and step 5, obtaining a final detection result by using a scale growth algorithm.

A quadrature output high-frequency RF divide-by-two circuit includes a pair of differential complementary logic latches. The latches are interconnected to form a toggle flip-flop. Each latch includes a tracking cell and a locking cell. In a first embodiment, the locking cell includes two complementary logic inverters and two transmission gates. When the locking cell is locked, the two gates are enabled such that the locked (i.e., latched) signal passes through both transmission gates and both inverters. In one advantageous aspect, the tracking cell only involves two transmission gates. Due to the circuit topology, the first embodiment is operable from a low supply voltage at a high operating frequency while consuming a low amount of supply current. In a second and third embodiment, the tracking cell involves a pair of inverters. The sources of the transistors of the inverters are, however, coupled together thereby resulting in performance advantages over conventional circuits.

The invention discloses a ship target detection method based on anadaptive layered high-resolution SAR image. The method comprises the steps that firstly a visual attention mechanism combining an image domain and a frequency domain is constructed, not only can better maintain the details of a saliency map, but also has an obvious speed advantage compared with other attention mechanisms; secondly,a candidate target region segmentation threshold value is obtained by adopting a mean dichotomy, so that instability caused by hard threshold value selection is eliminated; and finally, ship target fine detection is carried out by using a frequency domain accelerated block kernel density estimation method. Calculation burden caused by super-pixel segmentation is avoided due to the idea of region partitioning. The mismatch risk of a clutter model is eliminated through kernel density estimation. In addition, the execution efficiency of the detection method is further improved through a frequencydomain acceleration method of the detection method. In addition, compared with an existing high-resolution SAR image ship target detection method, the method has the advantages that the constant false alarm characteristic can be kept while the target is detected.
