High-power impulse pulse source used in air anti-stealth radar system

Abstract

The invention relates to the technical field of radar detection and discloses a high-power impulse pulse source used in an air anti-stealth radar system. The high-power impulse pulse source solves the problems of low peak value and low power of the pulse source of the air anti-stealth radar system in the traditional technology. The pulse source comprises a DC-DC module, a drive isolation module, a pulse generation module and a pulse shaping module; the DC-DC module and the drive isolation module are electrically connected with the pulse generation module; and the pulse shaping module is electrically connected with the pulse generation module. A 22-level avalanche transistor based Marx circuit is adopted to realize a high voltage peak value and a narrow half-peak width, and the pulse peak value voltage is greater than 2 kV, so that the operating distance of the radar system can be increased greatly; and the spectrum of the generated impulse signal is in a range from 0.1 GHz to 1 GHz, so that the frequency band range is wide, the requirement on anti-stealth can be met, and the high-power impulse pulse source is suitable for anti-stealth radar detection.

Description

technical field [0001] The invention relates to the technical field of radar detection, in particular to a high-power impulse pulse source used in an air-to-air anti-stealth radar system. Background technique [0002] Since the air-to-air anti-stealth impulse radar system requires the radiated signal to have a wide spectrum and a high voltage peak value, the output signal is a high voltage peak narrow pulse signal; however, the general RF front-end circuit cannot realize it. This requires a specially designed high-peak impulse pulse source for signal input to the antenna. The pulse source must meet the characteristics of high voltage peak, wide spectrum, small jitter, and small tailing. [0003] However, the pulse source of time-domain detection radar at home and abroad usually only has an amplitude of more than 1,000 volts, and the pulse width is several nanoseconds; this leads to insufficient power of the pulse source, and the detection distance is too short and the low-fr...
