An antichaff technique for tracking radar

The critical interference in radar systems is unwanted echo named clutter. Some important clutter includes echoes from land, weather (particularly rain), sea and deliberated chaff. Therefore, a military radar designer is faced with the problem of how to reject interference. In this paper, chaff elim...

Description
Summary:The critical interference in radar systems is unwanted echo named clutter. Some important clutter includes echoes from land, weather (particularly rain), sea and deliberated chaff. Therefore, a military radar designer is faced with the problem of how to reject interference. In this paper, chaff elimination methods such as Doppler processing and log-FTC are discussed and then an antichaff algorithm suitable in transient and steady descending state is introduced. Also, this technique is applicable and independent on chaff type and central frequency.
