Abstract-The conception of "advanced radar" is introduced an d put forward, while it is proved that the weakpoints of interference can still be employed. Meanwhile, the paper expounds the principle how Over-The-Horizon Radar(OTHR) works, and derives the OTHR interference equation. By listing the OT HR examples, it analyzes and calculates the equivalent power of the OTHR and the sensitivity of the receiver to build up a block diagram how the interferencer i s structured. Hence, the effective area is achieved, and OTHR can be intereferen ced effectively with not so high equivalent power.
Key words-OTHR; interference; advanced radar
