MIMO-ISS Waveform System

MIMO-ISS Waveform System is a “non-linear” digital communications, modulator-demodulator (i.e. modem) waveform system. Mathematically, the modem system operates based on the concepts and principles of “non-linear”, digital modulation theory.

Intermodulation Spread Spectrum (ISS) is a state-of-the-art, non-linear, angle-modulated spread spectrum digital modulation technique. Additionally, the ISS waveform is a constant-envelope and multi-dimensional wideband digital spread spectrum waveform system. ISS enables advanced digital communications systems that offer high immunity to interception, detection, and jamming. And lastly, ISS enables next-generation digital communications systems that offer high power efficiency, high spectrum efficiency, and high system capacity.

MIMO-DPR Radar System

MIMO-DPR Radar System is a “non-linear” digital radar system. The key architectural component of the MIMO-DPR System is a concept called “active” plenoptics. “Active” plenoptics is the integration of code division multiple access (i.e. CDMA) techniques with the discrete geometry algorithms into a new concept of radar systems.

Plenoptics is a concept adapted from computational photography. The word plenoptic is derived from Latin. Plenoptic means "full image" or "full vision". As such, the concept of digital plenoptic radar translates as follows:

As an integrated component of the MIMO-ISS System, MIMO-DPR operates using the Intermodulation Spread Spectrum (i.e. ISS) modem waveform system. In combination with the ISS waveform, these concepts enable advanced geometric digital radar systems that operate with high immunity to interception, detection, and jamming. Operationally, the MIMO-DPR Radar System enables improved detection, ranging, and parametric operations of the radar system.
