Research On Deinterleaving Algorithm Of Radar Pulses

It is a important problem to deinterleave the radar signals with pulse repeat interval in electronic countermeasures. Conventional algorithms are mainly based on histogram included cumulative difference histogram(CDIF) and sequential difference histogram(SDIF). With the increasing complexity of signal environment and radar singnals, these algorithms can not meet the practical demand. This paper introduced a new algorithm based on variable level of TOA difference with less operation and time ,based on compare of traditional deinterleaving algorithm. Computer simulation results have shown that the new algorithm can successfully deinterleave complex radar pluses in the high-pluse-density radar environments.This paper accomplish new algorithm on the base of hardware platform based on DSP and FPGA. It introduced detailedly the circuit structure of deinterleaving circuit and correlative program. At last, the circuit validate validity of algorithm successfully.
