Abstract :
In this paper we propose a new adaptive threshold mapping (ATM) technique for moving target detector (MTD) in modern radar. This technique is proposed to reduce the false alarms resulting from weather clutter and interference with relatively high Doppler frequency shift and MTD is not able to suppress it. The technique is based on controlling the receiver sensitivity according to the status of the output signal at the post detection. Also the technique is to control the signal processing path with relatively high probability of detection. The Simulation results show that this technique is a powerful solution to keep the post detection output with high probability of detection and minimum probability of false alarm rate compared with traditional MTD without ATM technique.
