WebTraditional methods use sub-sampling to take a single data point sample from an impulse waveform and reconstruct a complete waveform from average samples from multiple waveforms. Full waveform single-shot digitization has been demonstrated using high-speed analog to digital conversion (ADC). WebBistatic radar is a radar system comprising a transmitter and receiver that are separated by a distance comparable to the expected target distance. Conversely, a conventional radar in which the transmitter and receiver are co-located is called a monostatic radar.
