CANOPUS Baristatic Auroral Radar System (BARS)

The CANOPUS Baristatic Auroral Radar System (BARS) comprosed a ground-based radar array for remote sensing the high latitude ionosphere during the ISTP/GGS program. The system consisted of two 48 MHz coherent radars situated in Nipawin, Saskatchewan and Red Lake, Ontario. These radars illuminated the region roughly defined by the 333.0' and 340.5' EDFL meridians and the 63.0' and 67.8' EDFL latitudes via one broad transmitter beam and receive via 8 contiguous vertical fan beams. These beams plus range gating produced a two dimensional array of backscatter intensity and Doppler shift data. The CANOPUS program has been superseded by the CARISMA (Canadian Array for Realtime Investigations of Magnetic Activity).

CANOPUS 地基电离层测距雷达系统（BARS）由一套用于在ISTP/GGS项目中远程感知高纬度电离层的地面雷达阵列组成。该系统包括位于萨斯喀彻温省尼帕温市和安大略省雷德湖的两组48 MHz相干雷达。这些雷达通过单一宽波束照射由333.0°和340.5°东经度子午线和63.0°和67.8°东经度纬线大致定义的区域，并通过8个连续的垂直扇形波束接收信号。这些波束与距离门控技术相结合，产生了一个二维的回波强度和多普勒频移数据阵列。CANOPUS项目已被CARISMA（加拿大实时磁活动研究阵列）所取代。
