Abstract

PURPOSE:To obtain extremely effective information for fishery by displaying fish groups on a normal PPI and at the same time displaying the contents of density distribution of fish groups in a form of a strength distribution of echo signal. CONSTITUTION:An echo signal output of fish groups coming to a receiver 201 is successively written in a write circuit 105 and the output thereof is memorized in a memory circuit 106. While these operations are carried out, echo signals of fish groups are fed to a Braun tube 202 through a display switch circuit 108 and a normal PPI display of the image of the fish groups is presented. When writing is finished, the switch circuit 104 is operated and the signal memorized in the memory circuit 106 is read. These signals are stored in a form integrating echo signals corresponding to the respective directions, so that when these signals pass through the switch circuit 108 and are fed to the Braun tube 202, the strength of the density of fish groups is displayed.
