| 摘要: |
| 针对敌我识别（IFF）信号及战术空中导航（TACAN）信号侦察的需求，在传统相关干
涉仪测向模型基础上，改进设计出一种适合IFF和TACAN脉冲的高精度实时测向模型，并使用
甚高速硬件描述语言（VHDL）在FPGA内部实现。该模型可针对不同长度脉冲进行单脉冲快速
实时测向，可在检测到脉冲前沿后的3 μs内得到测向结果。VHDL的优化编程设计实现以及
工程的实际应用表明了该测向模型的实用性和有效性。 |

| Abstract: |
| According to the requirement of reconnaissance of Identification F
riend or Foe（IFF） signal and Tactical Air Navigation(TACAN) signal,based on co
rrelation interferometer algorithm，an optimized model for DOA(Direction of Arrival) e
stimation of IFF and TACAN signal is presented in this paper. The pulse DOA can be estimated real-time and precisely. The DOA result can be output in 3μs after the ascend edge of
pulse detected. VHDL is used to design the model. Both experimental and project
practice results verify the correctness and validity of the model. |
