Abstract
A system and method for high resolution radar imaging using a sparse array of time modulated ultra wideband (TM-UWB) radars. Two or more TM-UWB radars are arranged in a sparse array. Each TM-UWB radar transmits ultra wideband pulses that illuminate a target, and at least one receives the signal returns. The signal return data is processed according to the function being performed, such as imaging or motion detection. The TM-UWB radar array operates in several modes. In a first mode, each TM-UWB radar transmits and receives back scattering returns, and at least one TM-UWB radar receives forward scattering returns. In a second mode, each TM-UWB radar transmits but only one of the radars receives signal returns, both back and forward scattering. In a third mode, each TM-UWB radar transmits and receives back scattering signal returns, but neither receives forward scattering returns. TM-UWB radios can be used to perform other functions, such as handling communications between the radars and determining the distance separating one radar from another.
