Abstract
(EN) A DSSS radar (10) wherein a code generator (21), oscillator (32), antenna (24), and the like, repeatedly transmit a transmission signal modulated using a code that has a prescribed period and is emitted by the code generator; an A/D converter (45) samples, at a sampling period that is shorter than the period of the code, the code included in the reflected waves of the transmission signal that have reflected off an object; and a correlator (46) correlates a reference signal, in which the code generated by the code generator (21) is rearranged at an interval of Nsp, and the sampling data converted by the A/D converter (45) and thereby detects the object.
(FR) La présente invention porte sur un radar (10) à modulation à spectre étalé à séquence directe (DSSS) dans lequel un générateur (21) de code, un oscillateur (32), une antenne (24), et similaire, émettent de manière répétée un signal d'émission modulé à l'aide d'un code qui a une période prescrite et est émis par le générateur de code ; un convertisseur (45) A/N échantillonne, à une période d'échantillonnage qui est plus courte que la période du code, le code compris dans les ondes réfléchies du signal d'émission qui ont été réfléchies d'un objet ; et un corrélateur (46) corrèle un signal de référence, dans lequel le code généré par le générateur (21) de code est réagencé à un intervalle de Nsp, et les données d'échantillonnage converties par le convertisseur (45) A/N et détecte ainsi l'objet.
(JA)  DS‐SSレーダ10において、符号発生器21、発振器32及びアンテナ24等は、符号発生器21が発する所定周期の符号により変調された送信信号を繰り返し送信し、A/Dコンバータ45は、物体に反射した送信信号の反射波に含まれる符号を符号の周期以下のサンプリング周期でサンプリングし、相関器46は、符号発生器21が発した符号をNspの間隔で並べ替えた参照符号と、A/Dコンバータ45が変換したサンプリングデータとの相関を取ることにより、物体を検出する。
