초록 ▼

A method for compensating for the failure of an element in a phased array antenna assembly is provided. After failure of an element of the assembly, a composite pattern is generated from signals received by respective elements in the antenna assembly. This generated pattern is then compared to a standard composite pattern which was generated prior to the failure. Thus the necessity for remedial action can be assessed. If necessary, initial values for parameters associated with each element are assumed and an optimization is performed on the parameters. Consequently, a composite pattern can be generated which approximates the standard composite pattern. Once optimization has been achieved, the optimized parameters are applied to base settings for the assembly and operation of the phased array antenna assembly can be continued.

1. A method for compensating for the failure of an element in a phased array antenna assembly, the method comprising the steps of: a) generating a post-failure composite pattern from signals received by respective elements in the phased array antenna assembly after failure of an element of the phased array antenna assembly;b) comparing the post-failure composite pattern to a standard composite pattern generated prior to the failure to assess necessity for remedial action;c) if remedial action is necessary, assuming an initial value for at least one parameter associated with each element;d) if remedial action is necessary, performing optimisation on the parameters to generate a modified post-failure composite pattern which approximates the standard composite pattern;e) if remedial action is necessary, applying the optimised parameters to base settings for the phased array antenna assembly; andf) continuing with operation of the phased array antenna assembly;wherein the step of performing optimisation on the parameters comprises the steps of: i) generating the modified post-failure composite pattern based on the optimised parameters; andii) comparing the modified post-failure composite pattern to the standard composite pattern to assess whether acceptable performance is achieved;wherein the generating step a) comprises generating a post-failure curve of antenna pattern difference/sum ratio (Δ/Σ) plotted against offset angle (α) for the entire phased array antenna assembly;wherein the comparing step b) comprises comparing the post-failure Δ/Σ curve with a standard Δ/Σ curve generated prior to the failure, in addition to assessing necessity for remedial action;wherein the generating step i) comprises generating a modified post-failure curve of antenna pattern difference/sum ratio (Δ/Σ) plotted against offset angle (α) for the entire phased array antenna assembly; andwherein the comparing step ii) comprises comparing the modified post-failure Δ/Σ curve with the standard Δ/Σ curve generated prior to the failure, in addition to assessing whether acceptable performance is achieved. 2. A method according to claim 1, wherein: the generating step a) comprises generating the post-failure Δ/Σ curve using a monopulse measurement for the entire phased array antenna assembly; andin step b), the standard Δ/Σ curve generated prior to the failure comprises a monopulse measurement generated curve. 3. A method according to claim 1, wherein the parameters are phase and amplitude. 4. A method according to claim 1, wherein the element is a module comprising an antenna element. 5. A method according to claim 1, wherein the element is a sub-array comprising at least one module, the, or each, module comprising an antenna element and each parameter being associated with the, or each, module of the sub-array. 6. A method according to claim 5, wherein the applying step e) applies the optimized parameters to modules in selected sub-arrays of the phased array antenna assembly. 7. A method according to claim 6, wherein the optimized parameters are applied to sub-arrays located directly adjacent to the failed sub-array. 8. A method according to claim 6, wherein the optimized parameters are applied to sub-arrays located remotely from the failed sub-array in a balanced manner. 9. A method according to claim 5, wherein the applying step e) applies the optimized parameters to modules in all sub-arrays of the phased array antenna assembly. 10. A phased array antenna assembly comprising: a plurality of modules, each module comprising an antenna element; anda controller, for controlling the phased array antenna assembly, configured to perform a method according to claim 1. 11. A radar installation comprising a phased array antenna assembly according to claim 10.
