摘要

为了从电子设备产生可检测的谐波雷达响应,所需的目标功率与蜂窝基站直接下方观察到的功率相当。而且,从目标发射的信号通常很弱。这种微弱的信号不能被雷达本身产生的谐波所掩盖。因此,要对非线性雷达目标进行探测,必须具有高发射功率和高线性度。本文提出了一种在输出功率为7w、发射频率为800mhz ~ 1ghz范围内实现135 dBc谐波失真的技术。

Linearization of a harmonic radar transmitter by feed-forward filter reflection
In order to generate a detectable harmonic-radar response from an electronic device, the required power-on-target is comparable to that observed directly below a cellular base station. Also, the signal emitted from the target is often very weak. This weak signal must not be masked by harmonics generated by the radar itself. Thus, high transmit power must be provided with high linearity for detection of a nonlinear-radar target. In this paper, a technique is presented which achieves better than 135 dBc harmonic distortion at 7 W output power, at transmit frequencies between 800 MHz and 1 GHz.
