Abstract
An electronic warfare (EW) simulator is presented to investigate and evaluate the tracking performance of radar system under the electronic attack situations. The EW simulator has the input section in which the characteristic parameters of radar threat, radar warning receiver, jammer, electromagnetic wave propagation, and simulation scenario can be set up. During the process of simulation, the simulator displays the situations of simulation such as the received signal and its spectrum, radar scope, and angle tracking scope and also calculates the transient and root-mean-squared tracking errors of the range and angle tracking system of radar. Using the proposed EW simulator, we analyze the effect of concealment according to the noise and signal powers under the noise jamming and also analyze the effect of deception by calculating errors between the desired value and the estimated one under the deceptive jamming. Furthermore, the proposed EW simulator can be used to figure out the feature of radar threats based on the information collected from the EW receiver and also used to carry out the electronic attacks efficiently in electronic warfare.
Highlights
The collection and analysis of electronic intelligence have been regarded as one of the most important factors for improving the survival rate of friendly forces in modern electronic warfare (EW)
The radar warning receiver (RWR) receives radio frequency (RF) signals radiated from radar threats and extracts the characteristic parameters from the RF signals in which the features of radar threats can be included
We present an EW simulator that includes the modules of antenna, intermediate frequency (IF) conversion, automatic gain control (AGC), constant false alarm rate (CFAR) detection, range tracking, angle tracking, and velocity estimation for radar threat; the module of noise jamming, range deceptive jamming, velocity deceptive jamming, and range-velocity complex jamming for electronic attack; the motion control module for aircraft with RWR and jammer; the module of signal attenuation, frequency shifting, and multipath spreading for the propagation of electromagnetic wave
Summary
The collection and analysis of electronic intelligence have been regarded as one of the most important factors for improving the survival rate of friendly forces in modern electronic warfare (EW). To examine and verify the performance of various learning algorithms in a realistic and detailed EW situation, we need an effective simulator which has the essential elements of EW, such as detecting and tracking radar threats, jamming for electronic countermeasures or attacks, propagation of electromagnetic waves, and simulation of battle scenarios. We present an EW simulator that includes the modules of antenna, intermediate frequency (IF) conversion, automatic gain control (AGC), CFAR detection, range tracking, angle tracking, and velocity estimation for radar threat; the module of noise jamming, range deceptive jamming, velocity deceptive jamming, and range-velocity complex jamming for electronic attack; the motion control module for aircraft with RWR and jammer; the module of signal attenuation, frequency shifting, and multipath spreading for the propagation of electromagnetic wave. We summarize our result and discuss further research issues
