Consultation with a design engineer for magnetron radars (marine radars) is required

[Art_Sh]

Consultation with a design engineer for magnetron radars (marine radars) X-band is required. I am interested in questions related to the processing of the received signal, whether it is possible to replace the waveguide antenna with a compact antenna array through a waveguide-coaxial transition. The final task is to make a radio rangefinder.
