Current paper is about evaluation of measurement errors at distributed digital radar system with limited network bandwidth. Radar system considered under this paper consists of 2 main blocks: ADC convertor that digitalize raw radar signal and block of secondary data processing. Problem is states as following. ADC generates amplitude matrix by signals from radar. The paper refer to comparison of data transmission protocols between 2 physical hardware (PC based) connected into network. The paper presents the results of data transmission experiments on charts. One of the results of the experiments that data transmission speed does not directly depend on CPU, memory, network utilization. Based on the experimental values of data transmission speed as main result of the paper given charts of dependency of maximum size of amplitude matrix and measurement error for typical radar system. 

Keywords: radar measurement, digital signal processing, data transfer, distributed information system, measurement error.
