  • Publication number: 20170285137
    Abstract: A radar system, such as a weather radar system, includes a radar antenna and a processor. The processor is configured to cause a first radar beam to be provided using a first portion of the radar antenna. The processor is configured to cause a second radar beam to be provided using a phase adjusted portion of the antenna and a remaining portion of the radar antenna. A radar method and system can allow multiple low-loss overlapping radar beams to be rapidly generated to support a sequential lobing process which may be used to generate intra-beam target angle estimates. The production of these overlapping beams does not require mechanical antenna movement but beam selection is controlled by a simple electronic switch in some embodiments.

  • Patent number: 9409151
    Abstract: A method for calibrating an ESA radar to mitigate degradation of its radiation system. The radiation system includes the distribution manifold, the ESA radiating elements and the radome the ESA may be operating through. Sensing of degradation takes place both locally with a switchable matched load to identify individual ESA element characteristics and globally with target based radar return data. The data generated by this sensing of both local and global characteristics is then used to modify available ESA element complex weighting to produce a desired far-field radiation pattern.

  • Patent number: 9128189
    Abstract: A device and method is disclosed for a hybrid multi-mode airborne and rotary wing radar Electronically Scanned Antenna (ESA). Pulsed Radio Frequency Integrated Circuit (RFIC) Transmit and Receive Modules (TRM) are nested with Frequency Modulated Continuous Wave (FMCW) transmit elements within the aperture of an ESA. FMCW elements only transmit while the pulsed TRM receive both the pulsed return and the FMCW return. During the hybrid configuration, both the pulsed and FMCW performance is limited to less than the full ESA aperture. In an alternate configuration, individual TRM are configured for transmit and receive of both FMCW and pulsed signals are coupled within the aperture of the ESA. The individual elements offer full aperture performance in both pulsed and FMCW operation. A diplexer controls channel deconfliction between the pulsed and the FMCW transmissions/receptions while a switching network directs the individual elements to hop between the pulsed and FMCW modes.

  • Patent number: 9019145
    Abstract: A weather radar system is coupled to a weather radar antenna. The weather radar system includes a processor for combining or summing portions of the radar return data to obtain a null. The processor associates the null with the ground (e.g., steers the null toward ground or processes data so that the null corresponds to ground) to obtain a null to alleviate ground clutter when sensing weather. The null can be a single null or multiple nulls associated with different ranges.

  • Patent number: 8909471
    Abstract: A position determining voting system that uses Doppler information from an on-board weather radar to improve the system's accuracy and/or fault tolerance includes a comparison function and an error integration function. The comparison function is used to monitor the independent position sources for correct operation, comparing and identifying a position source that should not be used based on its relative error compared with the other position sources and their characteristics. The integration function provides corrections to relative position sources by integrating the data from multiple absolute position sources when they are mutually consistent.
