| titleOfInvention | Indicator of reflective information |
| abstract | PURPOSE:To analyze the density of a reflection body and its depth distribution, etc. intuitively and quickly, by displaying an integral value of a reflected wave of every minute depth range by a graph in accordance with each depth. CONSTITUTION:A reflected wave from a shoal of fish, etc. of each depth is corrected like an exponential function against diffusion by a TVG voltage oscillator 6, by an amplifier 7, and is stored in a storage device 11 at every minute depth range DELTAr through an A/D converter 10. This storage contents after read-out are corrected as to absorbed portion, too, by an attenuation correcting means 17, and an integral value of the reflected wave of every range DELTAr is calculated by a square-law circuit 18, an adding means 19, etc. Also, average processing of a division by a K-value, a detecting distance L, etc., which are dicided in accordance with the transmitting condition is executed by dividing means 31, 32, scattering intensity of each depth is decided, and a deflection curve Q corresponding to the depth is recorded on recording paper with a pen 40 together with a fish shoal detecting signals F1... of each depth. Accordingly, the density of a reflection body such as a shoal of fish, etc., and its depth distribution are analyzed intuitively on the recorded curve Q and signals F1.... |
