Jamming Structure of LFM Pulse Compression Radar Based on Digital Channelization
Firstly, this paper briefly introduces the basic principle of Linear Frequency Modulation (LFM) pulse compression radar and proposes the jamming structure of LFM pulse compression radar based on digital channelization. Based on this, channelized receiving and transmitting parts are elaborated in detail. In the channelized receiving part, a new method of applying Interpolated Finite Impulse Response (IFIR) filter to polyphase filter channelization structure is proposed. In the channelized transmitting part, an efficient channel synthesis structure based on IFIR filter is proposed. The simulation results verify the correctness of the structure, solve the problem that filter order increases with the narrowing of transition band, and effectively improve the acceptance of radar signals and the operational efficiency of the system.
