Abstract :
A wideband harmonic radar for tracking very small wood frogs in a high clutter environment is described. The one watt peak power radar transmitted in the 5.8 GHz ISM band and received in the 12 GHz satellite TV band. By transmitting a 150 MHz bandwidth linear frequency modulated waveform and exploiting the frequency doubling property of the harmonic tag to increase the bandwidth to 300 MHz, a range resolution of 1.6 feet was demonstrated. Furthermore, by resolving transmitter leakage and multipath, and by coherently integrating the tag return, the wideband harmonic radar sensitivity was improved by 20 dB over a comparable CW harmonic radar.
