摘　　要：线性调频脉冲（Ｃｈｉｒｐ）信号技术是海洋平面高度测量的关键技术，在国外利用卫星测量海面高度计中已得到广泛应用。８０年代后期，我们开始摸索Ｃｈｉｒｐ信号技术的应用。１９９５年进行了以飞机为载体的高度计平台海上飞行实验，圆满获得了平均海平面高度数据和波高数据，其波高分辨率为０．７５ｍ。这一新技术应用成功。 Chirp signal technique is one of the key techniques for measuring sea surface altitude.Using altimeter aboard satellite to determine the altitude of sea level have been adopted at abroad.In the late 1980s,we had begun with learning technical skills through trail and error.Up to 1990 we had carried on a airflight by altimeters aboard a plan and achieved data of sea level and wave altitude with wave altitude resolution in 0.75m.This technique experiment is newly establish in China.
