In this paper, an improved wide-band 90 degrees Schiffman phase shifter is presented by using a back to back microstrip line.

在此提出了一种改进的宽带移相90度希夫曼提出使用背对背微带线。

High resolution range profile(HRRP) is the projection vector sum of target scattering point echoes acquired by wide-band radar along the direction of radar line-of-sight(LOS).

高分辨 距离像（HRRP）是宽带雷达获取的 目标散射点子回波沿雷达视线方向的投影矢量和。
