“…The close proximity of radome to the antenna affects its radiation pattern and leads to the attenuation of radiated energy, causes antenna principal beam deflection from the expected bore sight and degrades side lobe levels (SLLs). These arguments are quantified as EM performance of radome in terms of transmission efficiency, boresight error (BSE) and SLL degradation [1][2][3][4][5][6] . The transmission efficiency and SLLs will have impact on radar detection capabilities and BSE on the tracking accuracies [7][8][9][10][11] .…”

The conventional fighter aircrafts are often equipped with fire control radar (FCR) using mechanically scanned antenna (MSA) with passive slots enclosed with monolithic conical radome. When the fighter platforms get upgraded with the modern active electronically steered array (AESA) FCR for better mission capabilities, even though radome change is desirable for optimum performance of AESA, it may not be feasible due to development time. This necessitate the evaluation of AESA radar with the existing monolithic radome. Hence active antenna aperture radiation pattern is required to be assessed with monolithic radome. To address this issue, simulation is preferred over physical testing, due to the reduced cost, time and complexity in measurements and ability to verify compatibility. In the present paper, the influence of monolithic radome on the active antenna radiation patterns are simulated and analysed. The characterisation studies helped for better optimisation of active aperture, optimum size for new radome development and additional space on fighter platforms that can be used for integration of new subsystems. Simulations are performed at two different locations of antenna inside radome. Experimental validations have been carried out to prove the efficacy of simulated results, which are in agreement.

“…This plate is tangent to radome surface in corresponding point. The calculation for re-reflection from radome inner surface is carried out by the same way, but we calculate the reflection filed in model problem about the passing of electromagnetic wave through two-layer plane-parallel plate [9]. In this case the electromagnetic wave falling to two-layer plate is passed through radome wall previously (path 2, fig.1).…”
