- 変調信号(18)が時間的に均一に分布しており、その振幅が、受信されるパルス(10)の量子化の際の量子化段階(13)又はこのような量子化段階(13)の整数倍に相当している、請求項2に記載の方法。
- 走査されかつ組をなすパルス(14)の数と変調信号(18)が通過する量子化段階(13)の数が、公約数を持たない、請求項3に記載の方法。
- 変調信号(18)が平均値を持たない、請求項1〜4の1つに記載の方法。
- 変調信号(18)がのこぎり波状信号である、請求項1〜5の1つに記載の方法。
- 変調化段階(13)が、請求項2〜6の1つに記載の変調信号(18)に応じてシフト又はスケーリングされる、請求項1に記載の方法。
- 受信されるパルスが、請求項2〜6の1つに記載の変調信号(18)に応じてスケーリングされる、請求項1に記載の方法。
- 受信されるパルス(10)が、請求項2〜6の1つに記載の変調信号(18)に応じて移相される、請求項1に記載の方法。
- 送信されるパルス信号(6)の時間的長さ及び/又は信号伝搬時間が、請求項2〜6の1つに記載の変調信号(18)に応じて変化される、請求項1に記載の方法。
- 請求項1〜10の1つに記載の方法を実施するための装置であって、特に自動車により連行可能で送信機(3)及び受信機(4)を持つ間隔センサ(5)を備え、送信機(3)は電磁パルス信号を送信し、受信機(4)は物体(2)の所で反射される信号(7)をパルス(10)の組をなす列の形で受信するようになっており、受信されるパルス(10)と変調信号(18)とを重ねる変調手段を備え、走査されるパルス(14)を得るため各パルス(10)を量子化する量子化手段を備え、互いに走査されるパルス(14)を加算する処理手段を備えている装置。
