Future radar systems will need to be adaptive and reconfigurable to allow for adequate sharing of the spectrum with wireless communication systems. This chapter has described several algorithms that facilitate the optimization of transmitter circuitry andradarwaveforms. The goals of these approaches include (1) ensuring desiredradar range/Doppler resolution characteristics, (2) achieving high powerPAE, and (3) spectral compliance to minimize the interference to other spectrum users. Algorithms for the fast tuning of the power amplifier load impedance, as well as simultaneous tuning of load impedance with input power or bias voltage, have been demonstrated to locate the optimal solution within a feasible number of required measurements.
