 note = {自立航法用機上ドプラレーダで航空機の速度ベクトルを求める場合,ドプラ受信信号が雑音性信号であるので,正確な中心周波数の決定とS-N比の改善のため周波数追跡装置が用いられる.本論文では,同期検波法を用いた周波数弁別回路の雑音性入力信号に対する解析と,これを用いた周波数追跡装置について理論的かつ実験的検討を行なった., The frequency tracker of doppler radar is analyzed here, which would be applied to the velocity computation of an aircraft for self-contained navigation. The radar signal is assumed to be the stationary Gaussian noise having the spectrum spread about 1/10 of the doppler frequency (I. e. the center frequency of doppler signal). The frequency tracking is performed by the servomechanism composed mainly of the synchronous detection (S-D) type of frequency discriminator and the voltage controlled oscillator. Experimental results are also given showing good coincidence with the theoretical analysis., 資料番号: SA0125343000},
