Problems solved by technology

[0003] The above-mentioned measurement method mainly has the following problems: one is that the measurement period is long and the efficiency is low
Second, the time span is large and the precision is low
The measurement time span is long, resulting in a long time interval between the background measurement and the target measurement. Therefore, the amplitude and phase drift of the target radar scattering hotspot measurement system and the environmental factors of the test field will change greatly, and the background cancellation cannot be completed well. , resulting in a decrease in the confidence of the target radar wave scattering hotspot test and a reduction in the accuracy of the measurement results
Third, there is a lot of interference caused by personnel entering the site. During the entire measurement process, personnel are required to enter the site to complete operations such as movement, adjustment, and measurement. Interference is artificially added, including the interference of personnel themselves and the interaction between personnel and targets, systems, etc. Mutual coupling interference, because the personnel are active in the field, cannot be eliminated by background cancellation, thus increasing the target radar wave scattering hotspot test error
Fourth, artificial positioning is random and has low precision
Since the operations of the moving target radar scattering hotspot measurement system and the adjustment of the antenna beam pointing of the system are all done manually, each measurement point needs to be repeatedly operated, and the manual positioning is random. The distance error between targets is large, which affects the accuracy of the measurement results of radar wave scattering hotspots of the target to be measured
