The paper discusses the features of calculating the detection range of marine targets for continuous-radiation radars of meter wave range. The information is provided on the prospects for using meter wave-length range for long-range detection of small targets, such as small boats and unmanned aerial vehicles, which make the development of low-cost mobile radars with chirp signals relevant. Limitations of tactical and technical characteristics of radars associated with the stability of master oscillators, Doppler velocity and the duration of coherent accumulation intervals are shown. The value of radar energy potential loss is estimated when using master oscillators with the frequency stability insufficient for coherent accumulation over long intervals of up to 10 seconds. The example of calculating the energy potential for detecting a boat at a distance of 11 km for the radar designed on the basis of systems used in P-18 M radar produced in the Republic of Kazakhstan is given.
