It happens but it's not supposed to. A standard rule is that an Aegis ship needs to "sector out" other vessels in company when they are within a specified distance -- I forget the number. Among the more vulnerable equipments are the EW receivers. The AN/SPY-1 sends a pseudo-random pulse train. When you hear one on a suitable receiver, it sounds like corn popping. No joke. Almost all modern radars send some sort of PN coded pulse (e.g. a Barker code) to be used in pulse compression so the peak/average power ratio is limited. A few radars use linear FM chirps. |
