Abstract:
(EN) In the present invention, a transmission unit (1) generates a transmission signal, which is obtained by multiplying a pulse signal that has been subjected to linear FM modulation by a first window function. A pulse compression unit (6) uses, as a reference signal, a signal obtained by multiplying a first standard signal, which is obtained by multiplying the pulse signal by a second window function different from the first window function, by the complex conjugate of a second standard signal, which is obtained by multiplying the pulse signal by a third window function that is an independent function from the second window function, and dividing the resulting signal by the complex conjugate of the transmission signal. The pulse compression unit (6) uses the reference signal to subject a received signal to pulse compression.
(FR) La présente invention concerne une unité de transmission (1) générant un signal de transmission, obtenu par multiplication d'un signal d'impulsion ayant été soumis à une modulation FM linéaire par une première fonction de fenêtre. Une unité de compression d'impulsions (6) utilise, en tant que signal de référence, un signal obtenu par la multiplication d'un premier signal standard, obtenu par la multiplication du signal d'impulsion par une seconde fonction de fenêtre différente de la première fonction de fenêtre, par le conjugué complexe d'un second signal standard, obtenu par la multiplication du signal d'impulsion par une troisième fonction de fenêtre constituant une fonction indépendante de la seconde fonction de fenêtre, et par la division du signal résultant par le conjugué complexe du signal de transmission. L'unité de compression d'impulsions (6) utilise le signal de référence afin de soumettre un signal reçu à une compression d'impulsions.
(JA) 送信部(1)は、リニアにFM変調されたパルス信号に第1の窓関数を乗じた送信信号を生成する。パルス圧縮部(6)は、パルス信号に第1の窓関数とは異なる第2の窓関数を乗じた第1の基準信号に対して、パルス信号に第2の窓関数とは独立した関数の第3の窓関数を乗じた第2の基準信号の複素共役部分を乗算した信号を、送信信号の複素共役部分で除算し、これを参照信号とする。そして、パルス圧縮部(6)は、受信信号に対して参照信号を用いてパルス圧縮を行う。
