A novel radar energy control strategy based on an Interacting Multiple Model Particle Filter (IMMPF) tracking method is presented in this paper, which controls the radiated power of radar according to predicted tracking Cramér-Rao Lower Bounds (CRLB). Firstly, the computation model of the CRLB as the relation model between the radiated power and the tracking performance is built. Secondly, the power...
In recent years, the cognitive radar (CR) with waveform diversity has exhibited significant performance improvements over the traditional fixed waveform radar and has become an area of vigorous research and development. A novel waveform selection strategy based on wind driven optimization (WDO) technique is proposed in this paper. Firstly, the predicted tracking Cramér-Rao Lower Bounds (CRLB) model...
A new search algorithm for phased array radar which is based on radio frequency stealth is proposed in this paper. When there is no indication information, parameters including the dwelling time and the average power are optimized by sequential quadratic programming (SQP), and a minimum energy cost model is set up by using Grey Relational Grade (GRG). The surveillance area is divided into several...
In order to extract robust features for radar high-resolution range profile (HRRP) recognition, a feature extraction method using circular convolution coefficients of HRRP is proposed in this paper. The features extracted by the proposed method represent the HRRP structure information which is more robust compared with local details. Moreover, this feature can make up for the loss of HRRP local details...
Pixel method which is enlightened from the graphic electromagnetic computing (GRECO) is introduced in this paper and realized by OpenGL and VC programming. Using simulation data, the wideband features of the target can be obtained for radar automatic target recognition(RATR). Some of the calculated features including RCS, range profile, and SAR image which are also refered to zero-dimensional image,...
