Ultrawideband radar

The author discusses the characteristics of ultrawideband radar and makes qualitative comparisons with narrowband systems. He notes that ultrawideband radars use signal bandwidths greater than 25% of center frequency. Conventional radio and radar signal bandwidths are generally less than 1% of center frequency. Using ultrawideband signals gives a range resolution smaller than most military targets. It is further pointed out that ultrawideband impulse signals can provide a capability for target imaging and identification through resonance characteristics. The added capabilities gained through ultrawideband signals are balanced by needs for complex receiver and signal processing.<>
