| Abstract: | Power combination technology includes circuit combination and space combination.It is adopted to combine many kilo-volt nanosecond ultra-wide band(UWB) pulse sources into a MW pulse source of an impulse radar.The UWB impulse radar target-detection system including a power combination solid state pulse source,a UWB planar horn antenna array for transmitting and receiving,a quadrature demodulation receiver and a computer for controlling is designed,and its theory is presented.The field test results confirm that the system is feasible and the signal processing is correct and effective.The results can provide a practical basis for the development of the radar technology of the high power impulse radar. |
