小球靶标为测试雷达系统提供了一种经济安全的试验方法。即使实际尺寸很小,也可以提供一大的雷达有效截面的靶标。其形状解决了靶标外形问题,其速度曲线图是可以再现的。新的三角架已经完成,并用于雷达外场试验中。一种新的设计也实际上解决了在第一个三角架中发现的不稳定性问题。予测速度分布图很可能实现。速度分布图的测量应由各个不同距离上用计时技术完成。这也可以由雷达技术所已取得的速度数据来证实。在未来的试验中,钢球需与铅球作一比较。如果钢球证明合乎要求,那末钢球应在未来的雷达试验中采用。钢球之优点是能制成十分完美的球体,而且由于钢球的强度而能少受损伤与变形,有可能因采用现在的枪而需对球尺寸作某些减小或者因采用钢球而改造枪镗,以防止枪被卡住与毁坏。尺寸的减小不会对雷达有效截面造成大的影响。目前正在鉴定0.375时直径的钢球。这些球具有α/λ0.I6.雷达有效截面为2.49厘米~2。或-36.0分贝/米~2。这比α/λ为.17及有效截面为—35.6分贝米~2的小铅球较好。
Ballistic targets provide a cost-effective test method for testing radar systems. Even if the actual size is small, it is possible to provide a large target of radar effective cross-section. Its shape solves the target profile problem and its velocity profile is reproducible. The new tripod has been completed and used in radar field tests. A new design actually solved the instability problem found in the first tripod. The predicted velocity profile is likely to be achieved. The measurement of the speed profile should be done by timing techniques at various distances. This can also be confirmed by the speed data already obtained by radar technology. In the future test, the steel ball should be compared with shot put. If the ball proves to be satisfactory, the ball should be used in a future radar test. The advantage of a steel ball is that it produces a perfectly spherical body that can be less damaged and deformed due to the strength of the steel ball and may require some reduction in the ball size due to the current gun or because of the ball Remodeling a gun to prevent the gun from being stuck and destroyed. The reduction in size will not have a large effect on the effective radar cross-section. A diameter of 0.375 ball is currently being identified. These balls have α / λ0.I6. The effective radar cross section is 2.49 cm ~ 2. Or -36.0 dB / m ~ 2. This is better than a / λ of .17 and an effective cross section of -35.6 dBm ~ 2.
