Dynamically tunable notch filter |
摘要 |
A dynamically tunable notch filter is used within a continuously transmitting laser radar system for filtering narcissus signals generated from a continuous linear frequency modulated chirp transmission signal at the transmission aperture antenna with the filter including mixing and band pass filtering at the narcissus dynamic frequency to eliminate the unwanted narcissus signals varying over the dynamic frequency range of the narcissus signals, and to also eliminate unwanted target images, for improved resolution and detection of low level reflected target signals which are often obscured by the presence of the relatively high-level unwanted narcissus signals.
