| Abstract: | In order to detect IFF signal in non-cooperative condition,this paper analyzes the characteristics of IFF answer signal, designs the way of IFF answer signal real-time detection. The key techniques such as digital orthogonal transformation techniques based on polyphase filtering, envelope detection and pulse parameter measurement are analyzed in this paper. Finally, the real-time detection of pulse signal is implemented and tested in FPGA. The results show that this technique can meet the requirements of engineering aoolications. |
