Necessity and possibility of taking into account of space and time domain parameters of interfering reflections from the underlying surface in the design of anti-interference airborne radar stations for air surveillance

Abstract

The development of anti-interference radar stations is impossible without the knowledge of interference parameters. The main difficulty of designing of anti-interference airborne radar stations for air surveillance is associated with the suppression of reflections from the underlying surface. In order to estimate the azimuthal-velocity parameters of reflections from the underlying surface in airborne surveillance stations with unambiguous distance measurement we implemented the simulation model of digital output signals of a coherent radar receiver. During the model development we used digital maps and an antenna with low side lobe level. With the help of simulations we have justified the necessity and possibility of development of anti-interference airborne radar stations with low-channel design and simultaneous application of direct inter-period and inter-channel correlation connections.
