Dispersive target detection

A process comprising:

• a) transmitting a combined frequency agile signal waveform comprising a combination of:
• i) a first frequency agile signal waveform comprising a first multitude of frequency elements between:
• a first lower frequency and a first upper frequency;
• and
• ii) a second frequency agile signal waveform comprising a second multitude of frequency elements between a second lower frequency and a second upper frequency, wherein:
• (1) the second lower frequency is shifted from the first lower frequency by a first delta frequency;
• and
• (2) the second upper frequency is shifted from the first upper frequency by the first delta frequency;
• b) receiving a combined return signal;
• c) splitting the combined return signal into at least the following:
• i) a first return signal comprising a first in-phase component and a first quadrature phase component;
• ii) a second return signal comprising a second in-phase component and a second quadrature phase component;
• d) generating a second phase shifted return signal by phase shifting the second return signal by the first delta frequency;
• e) generating a combined return signal comprises combining the first return signal and the second phase shifted return signal;
• and
• f) determining a probability of a potential target when the combined return signal exceeds a threshold.
