Abstract

This paper discusses a new approach for target detection performance improvement in monostatic pulsed radar in presence of clutter based on Time Varying Gain Amplifier (TVGA). This new approach is used to compensate for power loss due to range in the received echo, which increases the input dynamic range and the sensitivity of the radar receiver. A constant threshold is selected for detection across the entire detectable range. The new approach is achieved by time controlling the received power, which enhances the detection performance in the presence of ground clutter and jamming effect, the simulation of a complete monostatic pulsed radar is considered with the environmental effect. The results shows thatafter applying the TVGA the signal can be detected effectively with a fixed threshold and gives more sensitivity and a wide dynamic range.
