A method of detection performance modeling in jamming condition based on radar network system

Model of radar signal-to-noise ratio and signal-to-jamming ratio were given with full consideration of radar detection performance parameters and jamming parameters. Then signal-to-jamming ratio gain was analyzed with different electronic counter-countermeasures. At the same time, radar detection probability models with different target RCS fluctuation were built. Based on these, detection probability model was built based on radar network system. Finally, simulations of radar network system detection performance were given in jamming condition, and anti-jamming effect was analyzed when radar adopted electronic counter-countermeasures. Result of the simulations indicated that the model can be used as a way of radar network system detection performance evaluation.
