摘　　要：针对末敏弹单元红外探测扫描信号单一,识别和命中概率低的问题,提出了一种适用于多元红外探测的尺寸解算和定位方法。该方法的核心是对多元线阵红外探测器采集到的多路波形信号进行响应脉宽和时序获取,并联合高度信息求解热区尺寸。通过多路信号的响应元数和时序关系判别定位目标。对目标进行了尺寸解算和定位模拟实验,结果表明:多元探测利用所述方法可以获取目标尺寸和定位目标,验证了所提方法的有效性。A size calculation and positioning method suitable for multi-element infrared detection is proposed to address the problem of low recognition and hit probability when only one scanning signal is used for infrared detection of terminal sensitive ammunition.The core of this method is to obtain the response pulse width and timing of the multi-channel waveform signals collected by the multi-element linear array infrared detector,and combine height information to solve the size of the hot zone.Real-time positioning is achieved by identifying the position of the target based on the response elements and temporal relationships of different signal paths.The size calculation and positioning experiments are conducted on the target,and the results show that the proposed method can obtain the target size and determine the center position of the target using multivariate detection,verifying the effectiveness of the proposed method.
