Analysis of Key Technologies and Performances of Fire-Control Radar of Low Probability of Intercept

The key technologies of fire-control (FC) radar of low probability of intercept (LPI) are researched, and an analytical model is established and applied to conduct quantitative calculation and qualitative analysis of the relationship between the LPI advantage and maximal detection range in mainlobe interception mode with various time–bandwidth signals through a case study, so as to achieve the low intercept performance of fire-control radar and improve its effectiveness and survivability. It is found from analysis that the transmission energy needs real-time management based on prior information; both the peak power (PP) and pulse width (PW) of transmission signal of FC radar of LPI need to be quantitatively controlled, which is of referential significance for the design of FC radar of LPI.
