Abstract:

The detection performance of the four Network Radar operating models to spherical targets is researched when the total power of single pulse of the transmitters is definite. Analysis and simulation show that the more the node number is, the better the detection performance of rephased coherent netted radar (RPNR) and multiinput multioutput (MIMO) model is, and show that mobile windows (MW) and coherent metted radar (NR) is opposite. When the node number is definite, the detection performance of RPNR model is better than that of MIMO model, but the latter is better than that of MW and NR model. The MW model is the worst when the signaltonoise ratio (SNR) is lower, also the NR model is the worst when the SNR is higher.

Key words: noncoherent integration, network radar, spherical targets, detection performance
