A commonly accepted airborne phased array radar model simplifies
the analytical derivation by assuming a waveform is perfectly
matched in range and Doppler shift. This assumption means the
matched lter output is e ectively constant for all possible
received scatterer Doppler and range mismatches, greatly
simplifying the analytical development from that point forward.
This research removes the matched Doppler and range assumption and
examines the e ects of several common waveforms on the model's
delity along with the associated impact on radar performance, both
non-adaptive and adaptive. Analysis is completed using power
spectral density comparisons and the fully adaptive output signal
to interference plus noise ratio comparison. Results indicate that
the model's delity is impacted little by the Time Frequency Auto
Correlation Function. However, change in bandwidth from the
compressed waveforms does impact the model. Increased bandwidth
introduces more thermal noise which dominates clutter returns.
Therefore, the clutter problem becomes less di cult. The trade-o is
a reduction in the resolution capability of the clutter spectrum.
