摘要: |
为了解决相位编码准连续波雷达的回波遮挡问题,首先引入遮挡率函数和遮挡情况下
的回波主旁瓣比定量分析回波遮挡。在此基础上提出一种基于MAC(Multimode Arbitrary C
ode)序列的长短脉冲结合的波形设计方法,并给出了基于此方法的波形设计实例和相
应的仿真分析。仿真结果表明该波形设计方法能够有效解决相位编码准连续波雷达的回波遮
挡问题,实现远近目标的同时探测。 |

Abstract: |
In order to solve the echo eclipse problem in phasecoded quasicont
inuous wave(quasiCW) radar, the echo eclipse is quantitatively analyzed by us
ing echo eclipse ratio function and main lobe to side lobe ratio.
On this base,a phasecoded waveform design method based on multimode arbitrary
code(MAC) sequence and longshort pulse width is proposed, and an example of quasiC
W radar signal design based on this method is presented and simulated. Simulati
on results show that the echo eclipse problem is effectively solved as well as
the whole range target can be detected simultaneously. |
Key words: low probability of interception(LPI) quasi CW radar phase coded echo eclipse MAC sequence waveform design |
