Abstract

PURPOSE:To make it easy to change the arrangement and the aimed number of wave receivers and make it possible to output target signal without noise by sorting in a digital memory the shape of a wave receiver arrangement and the direction of a target signal and performing digitally treatment of the delay and the product and addition. CONSTITUTION:A plurality of target signal generators S and received wave arrangement data memories 4-7-1 and 4-7-2 that output respectively the shape of wave receiver arrangment and data on sampling cycle in accordance with the specification of a digital delay memory 4-2 that delays the signal of the signal generator S and a receiver number counter 4-6-2 and target memories 4-7-3 and 4-7-4 that output respectively the direction and intensity of the target in accordance with the specification of a target number counter 4-6-3 are provided. Then, delay necessary for the sample value of target signal is given by giving address of the delay memory 4-2 for each wave receiver and target, and the product of the delay and the intensity of the target are D/A converted by a converter U and the conversion is made input signal for wave receiver. With this setup the shape of arrangement and change of the number of targets are made easy and high precision of output signal can be attempted.
