Electromagnetic Interference Between Naval Employment Radars

The use of radars in the maritime environment has both civil and military applications. The effect of co-channel interference between radars deployed on different ships occurs frequently in several navies. This work proposes to develop a methodology to mitigate the effect of interference between radars operating at the same frequency. A hypothetical radar is used to simulate the effect of co-channel interference between ships, varying the azimuthal engagement angle and the distance between the ships. In the end, a topology of arrangement of ships in a column is obtained, with a maximum distance of 5.95 NM and an arrangement in line with a maximum value of 37.01 NM. This work shows that interference occurs between radars, being overly dependent on the angular condition of engagement due to the effect of the RCS (Radar Cross Section) of the interfering ship.
