现代雷达需要有较好的低截获特性,同时在大量低RCS目标出现后,雷达要增强对这些目标的探测能力,就必须降低信号处理的检测门限,然后通过数据处理的方法,沿目标的运动路径将回波幅度进行非相参积累,以降低虚警率。本文通过将低门限检测、卡尔曼滤波、动态规划法相结合的办法,将雷达可靠检测的信噪比降低6dB左右,相当于将雷达的最大作用距离提高了近30%,并给出了仿真结果。

Taking the power reflectivity measured by far field radar scattered cross-section method as the characterization indicator to appraise the absorption property,the absorption property of pure mortar and the influence of length and volume fraction of carbon fiber,mixing method,combined addition of carbon fiber and ferrite,temperature and humidity on the absorption property of carbon fiber mortar were investigated.The stealthy capability was calculated by a deduced evaluation equation of stealthy effectiveness.The results show that the absorption property of mortar in the high frequency range can be increased by adding carbon fiber,and a suitable length and volume fraction of carbon fiber are important factors for improving the absorption property of mortar.The absorption property of carbon fiber mortar made by the machine mixture is better than that by the artificial mixture,and it decreases with the increase of tem-perature and humidity or with the combined addition of carbon fiber and ferrite.The maximum radar detection range of carbon fiber mortar with an optimum mixture ratio is 80%—90% of pure mortar in the frequency range of 14—18 GHz.

采用远场雷达散射截面法测试的功率反射率为表征吸波性能的指标,研究了素砂浆的吸波性能以及碳纤维长度、碳纤维掺量、搅拌方法、复掺铁氧体、温度和湿度等因素对碳纤维砂浆吸波性能的影响,根据所推导的隐身效能评价公式计算了碳纤维砂浆的隐身能力。研究表明:掺入碳纤维只能提高砂浆的高频吸波性能;合适的纤维长度和体积掺量是提高砂浆吸波性能的决定性因素;机器搅拌方法制备的碳纤维砂浆的吸波性能好于人工搅拌方法制备的碳纤维砂浆;温度、湿度升高,或者复掺铁氧体、碳纤维砂浆的吸波性能均下降;最佳配比的碳纤维砂浆在14~18GHz的频段内,其雷达最大探测距离可降低到素砂浆的80%~90%。
