| 摘要 | PURPOSE:To improve altitude detection accuracy by comparing Doppler detected output voltage and the prescribed divided voltage of the Doppler detected output voltage before a fixed period and determining altitude. CONSTITUTION:A flying body 1 such as a cannon ball generates the Doppler detected output En at altitude Hn by way of an antenna 3, etc. by the reflected waves from a target 2. This output En is divided by a voltage dividing circuit 6 in accordance with the ratio alpha between the altitude Hn and the altitude Hn-1. On the other hand, when the count value of a counter 8 attains the count value corresponding to the time when the body 1 falls from the altitude Hn-1 down to Hn for a distance D, it is compared with the voltage En-1 having been held in a sample holding circuit 7, and whether the conditions of the equation I corresponding to the arrival at the altitude Hn or not is detected. By this constitution, the highly accurate altitude detection of whether initiating altitude was attained or not is accomplished. | ||||||
