The performance of a network radar system exposed to the jamming techniques have been considered. Universal signal and jamming models have been elaborated with the use of space-time functions, and the explicit expressions for calculating signal-to-noise ratio (SNR) at the output of the system as applied to the same have been obtained. Estimates have been derived to show that emitter range resolution errors have impact to the SNR value: At the value of root mean square and accuracy errors of range resolution less than 1% the SNR reduces by more than 10 times.
