| 摘要: |
| 雷达告警器(RWR)多用“告警小盒”法进行威胁鉴别，虚警率高是影响雷达告警器效能发挥
的关键问题之一。提出了一种新的告警器虚警机理，即对于RWR中相同频段内、方向也近似
相同的多个脉冲序列组成的信号流中，虽然这些序列各自不相关，且任何单一序列均与某“
告警小盒”指标相差很大，但可能有某些组合片段符合该“小盒”告警判决条件，从而产生
虚警。仿真结果表明了这种告警机理的存在，而且在某些条件下这种虚警率也相当高。 |

| Abstract: |
| “Warning Box” is often used in Radar Warning Receivers(RWR) for identificatio
n threats,but high FalseWarningRatio is one of key defects which af
fect RWR’s efficiency.A new kind of RWR false warning mechanism is introduced
. For the combined flow by several radars pulseseries which are in the same wa
ve
band,same orientations, but far different for a specific “Warning Box” and
have no relativity for each other,there do exist combining pieces in the series
flow that accord with the Box,thus false warning is produced.Simulation indic
ates such kind of false warning mechanism with a remarkable high ratio in given
conditions. |
| Key words: RWR threat discrimination Warning Box false warning ratio |
