Generation of Pulsed Power for Radar Application

Abstract

This paper proposes an efficient method for generation of high power train of pulses which are widely used in many fields. Pulse generators store energy in the form of electric or magnetic field for certain duration and by closing a switch at the load side, complete energy will be discharged to the load in the required form of pulses. The pulse generators are widely used in Radar application to drive magnetron loads with desired magnitude, pulse repetition frequency (PRF) and pulse duration or width. Line type modulator where a Pulse Forming Network (PFN) of type E is used as an energy storage element for generation of pulses. In this work, it is desired to produce rectangular pulses of magnitude 5 kV, PRF of 1.6 kHz and pulse duration of 4 microseconds with minimum rise time required for Radar application to drive load. MATLAB simulation is carried out in order to realize pulses of desired specification and a scaled down hardware setup is developed to verify the system performance.
