摘要

摘要:
針對雷達采取間歇輻射的射頻隱身管控措施，以雙站測向交叉定位為例，該文研究了輻射時間比與定位性能的影響關系。首先分析了雷達間歇輻射的管控方法，然后在載機做勻速直線運動的假設下，采用克拉美羅下界(CRLB)方法，建立了輻射時間比對定位精度的影響模型。最后給出了模型的求解步驟并進行了仿真驗證。仿真結果表明，不同輻射時間比對定位性能的影響不同，在初始距離為100 km，輻射時間比小于0.5時，定位收斂時間超過10 s，可以有效降低測向交叉定位的性能。

Abstract:
For the radio frequency stealth control measure of radar intermittent radiation, the relationship between radiation time ratio and positioning performance is studied which takes cross location with two stations as an example. Firstly, the control method of radar intermittent radiation is analyzed. Then, under the assumption of uniform linear motion of the carrier aircraft, the influence model of radiation time ratio on positioning accuracy is established by using the Cramer-Rao Lower Bound (CRLB). Finally, the solution steps of the model are given and verified by simulation. The simulation results show that different radiation time ratios have different effects on the location performance. When the initial distance is 100 km and the radiation time ratio is less than 0.5, the location convergence time exceeds 10 s, which can effectively reduce the performance of cross location with two stations.
