Digital multi-frequency CW radar is a kind of radar system which can detect multiple targets and acquire their moving parameters, elevations, azimuthes and ranges precisely by a simple equipment. 数字多频连续波雷达设备简单,可同时得到多个目标的运动参数、俯仰角、方位角以及距离的精确测量值。 2. Mu...
We also show the fundamental experimental results obtained in an athletic field using the radar fitted on a cage lifted by a crane. We could obtain stable estimation results on altitudes between 1.0m and 7.0 m. These results indicate that the multiple frequency CW radar is one of the ...
Digitized multiple frequency CW radar is a kind of new system radar.It can detect lots of targets and acquire different movement parameters as well.But it is hard to enlarge maximum unambiguous range while improving ranging accuracy at the same time.To deal with such a contradiction,stagger frequ...

From the perspective of hardware architecture, it utilises several different receivers with the same antenna and a highly precise frequency source. In signal processing, the concepts of Common Waveform (CW) and Correlation Waveform are introduced and defined for the first time. (2) For estimating...
Across-track resolution of a spaceborne synthetic aperture radar (SAR) system is limited by power and data rate constraints. The authors derive and discuss a new technique for increasing the across-track resolution of objects that do not change with time, using multiple surveys of the same area...
