  • Adaptive array
    Patent number: 7317427
    Abstract: An adaptive antenna array has array elements arranged in element rows and element columns and subarrays arranged in subarray rows and subarray columns, for which the subarray phase centers have non-uniform spacing. The adaptive antenna array provides good detection and tracking performance when used in a radar system, while being inexpensive and easy to manufacture. A radar system and a method of adapting a radar array both employ the above described adaptive antenna array.

  • Calibration method for receive only phased array radar antenna
    Patent number: 7199753
    Abstract: A method of calibrating a receive only, phased array antenna in its operating environment. Two transmit signals of different but unknown polarizations are used to calibrate the receive only antenna array, and the receive element locations and polarizations are accurately known. The method determines the complex weights on the antenna elements and the magnitude of the vertical and horizontal components of the calibration signal in the presence of multi-path signals as well as standard noise. Two different methods for calibrating are provided. A first method uses combinations of three elements to determine the calibration constants using small matrices and then averaging all the possible results for each element, and a second method solves for the calibration constants for all elements at one time using a singular value decomposition, but requires the manipulation of large, sparse matrices.

  • Technique for non-coherent integration of targets with ambiguous velocities
    Patent number: 6828929
    Abstract: A method for processing pulsed-Doppler radar signals to detect a target includes transmitting radar signals from a radar system according to a predetermined frequency technique including signals having frequency diversity, receiving signals within a frequency band, including a target return signal having a frequency indicative of the velocity of the target, and transforming the target return signal using a Fourier Transform having a variable frequency scale.
