摘　　要：本发明公开一种纯距离雷达组网单目标定位方法，解决在雷达组网对单目标进行定位的过程中，传统的野值识别方法不适合动态情况且实时性较差的问题。主要步骤包括：(1)对组网雷达进行组合进而获得交点坐标；(2)通过交点的距离和确定该交点所处位置的密集程度；(3)将交点的密集程度与聚类检测门限相比较，进而完成野值点识别及目标的定位。同传统方法相比，本发明易于工程实现且实时性、准确性较高，可以有效提高目标的定位精度。

主权项：1.一种纯距离雷达组网单目标聚类定位方法，其特征在于包括以下步骤：步骤1：将某一时刻N(N＞3)部雷达接收机R_i＝(x_i,y_i)^T(i＝1,2,…,N)测得的目标距离信息d_i送入雷达信号处理计算机；步骤2：初始化n_p为交点数量，初始化n_p＝1；n_max为交点数量最大值，χ₀为聚类检测门限，取χ₀∈(0,1)；n_g为密集程度高的交点数量，初始化n_g＝0；步骤3：计算交点坐标(1)任意选择三部雷达R_m＝(x_m,y_m)^T、R_n＝(x_n,y_n)^T、R_k＝(x_k,y_k)^T；(2)测得关于目标的交点坐标为： $<math><mrow><msub><mover><mi>x</mi><mo>^</mo></mover><msub><mi>n</mi><mi>p</mi></msub></msub><mo>=</mo><mfrac><mn>1</mn><mrow><mn>2</mn><msub><mi>L</mi><mn>1</mn></msub></mrow></mfrac><mo>[</mo><mrow><mo>(</mo><msub><mi>y</mi><mi>m</mi></msub><mo>-</mo><msub><mi>y</mi><mi>k</mi></msub><mo>)</mo></mrow><msub><mi>L</mi><mn>2</mn></msub><mo>-</mo><mrow><mo>(</mo><msub><mi>y</mi><mi>m</mi></msub><mo>-</mo><msub><mi>y</mi><mi>n</mi></msub><mo>)</mo></mrow><msub><mi>L</mi><mn>3</mn></msub><mo>]</mo><mo>-</mo><mo>-</mo><mo>-</mo><mrow><mo>(</mo><mn>1</mn><mo>)</mo></mrow></mrow></math>$ $<math><mrow><msub><mover><mi>y</mi><mo>^</mo></mover><msub><mi>n</mi><mi>p</mi></msub></msub><mo>=</mo><mfrac><mn>1</mn><mrow><mn>2</mn><msub><mi>L</mi><mn>1</mn></msub></mrow></mfrac></p><p class='subject'><strong>关键词：</strong><b class='type_ico_id'></b>雷达组网单目标 <b class='type_ico_id'></b>实时性工程实现交点坐标所处位置野值识别传统的野值点 <b class='type_ico_id'></b>聚类 <b class='type_ico_id'></b>门限 <b class='type_ico_id'></b>组网 <b class='type_ico_id'></b>雷达检测 </p><p class='class'><strong>IPC专利分类号：</strong>G01S13/06(20060101); G01S7/41(20060101)</p>
