为了优化谐波雷达对电子目标的探测，系统设计者必须选择合适的频率、功率级、收发器组件、天线和波形。这项工作的重点是雷达设计的一个权衡：发射波形的占空比与峰值功率。研究了单频脉冲。假设发射频带的总（平均）功率是固定的；然而，占空比和峰值功率是可调的。利用非线性雷达硬件仿真测量的谐波表明，为了最大限度地提高反射目标响应，减小发射机占空比和最大化峰值功率是有利的。
To optimize a harmonic radar for the detection of electronic targets, a system designer must select appropriate frequencies, power levels, transceiver components, antennas, and waveforms. This work focuses on one tradeoff for radar design: duty cycle vs. peak power, for the transmit waveform. Single-frequency pulses are studied. It is assumed that total (average) power in the transmit band is fixed; however, duty cycle and peak power are adjustable. Harmonics measured using a hardware simulation of a nonlinear radar demonstrate that, to maximize reflected target response, it is advantageous to minimize transmitter duty cycle and maximize peak power.
