Multi-false-target jamming, a typical active deception jamming mode, will have different effects on the radar with different-signal parameters. Based on the principle of constant false alarm (CFAR) detection, the principle and process of multi-false-target jamming to radar are discussed in this paper. Then the relationship between the detection performance and two parameters, the jamming to signal...
Repeating decoys (based on DRFM), through main lobe into the radar receiver, realistically simulate real target's echo in both time and frequency domain, and greatly affect radar regular operation of radar. This paper, based on the premise that the actual target is multi-feed radiation and the repeating decoy is single feed radiation, analyzes in theory and explains its physical essence from the perspective...
Based on the background of radar target detection and recognition of space precession targets, an experimental study on full-polarization micro-Doppler of those targets is introduced. The wide-band scattering properties of space precession targets are analyzed, and then the theoretical full-polarization micro-Doppler models are proposed. The scenario of the experiment is introduced, and the measured...
Repeating decoys (based on DRFM), through the main lobe into the radar receiver, realistically simulate real target's echo in both time and frequency domain, and cause serious threat to radar's search, identification and tracking. At the near distance, angular error caused by target's angular glint is an important noise source and it can be utilized to the discrimination of repeating decoys. At the...
With dynamical change of the environment, the optimal allocation of search resources is required for multi-area search of phased array radar. A parameter optimization model based on the weighted average discovering range of the penetration target is built in this paper. By joint search load allocation and search frame time adjustment optimal performance is achieved with initial search resources. Then...
