2 way DOVAPを用いた近接距離測定方式に関する研究

抄録

In order to improve the accuracy of measurement of DOPPLER type miss distance indicator (MDI) used to measure the miss distance between a flying body and a target by utilizing the DOPPLER effect of radio wave, the possibility of MDI of 2 way DOVAP type was investigated and a measuring method capable of obtaining the miss distance by the use of integration data of DOPPLER frequency obtained from the oscillograph of DOPPLER beat and from direction cosine data was found out.
In the present paper, the measuring principle of measuring method, the simulation test conducted to ascertain the establishment of the measuring principle, the results of the test, and the results of our investigation on the measurement error were described. It was also described in the present paper that the miss distances up to about 20m can be measured with an accuracy of within±1m of measurement error by this method and that the methods can make a measuring method which is practicable in the evaluation of the performance of precision guided flying bodies passing by at so near a distance as within 10m of miss distance.
