Abstract

A radar low sidelobe waveform design method belongs to the technical field of radar detection and is used to solve the problems of low stability and poor performance of suppressing autocorrelation distance sidelobe in the existing radar waveform design method. The present invention adopts the evolutionary projection algorithm to design the radar waveform. Compared with the existing waveform design method, the present invention has better waveform design robustness, avoids the disadvantages of poor stability of non-convex mathematical solutions due to the constant modulus of the waveform, and has more Low correlated sidelobes. By applying the method of the invention, conventional radar and MIMO radar can have better detection performance.

Description

technical field [0001] The invention relates to the technical field of radar detection, in particular to a radar low sidelobe waveform design method. [0002] technical background [0003] In modern warfare, African cooperative "reconnaissance" drones are playing an increasingly important role. As an important detection tool for countermeasures, ground-based radars have become the key to improving radar combat performance and battlefield survivability. important means. Especially in the shadow of strong scatterers such as lighthouses and high-rise buildings, the detection of small scintillation targets is becoming an important aspect of time-domain waveform design; at the same time, in order to make full use of the radar transmitter power, the waveform constant mode model has also become an objective requirement. To avoid the shading effect of strong scatterers, the waveform needs to have low autocorrelation sidelobes; the current representative solution is the cyclic algori...
