DBF architectures provide significant functionality enhancements for phased array radar. At the current state of digital technology, element-level DBF is often impractical for large arrays operating at high frequencies, so subarray level implementations are commonly used to reduce the digital receiver count. The choice of subarray architecture heavily impacts performance due to grating lobes and grating nulls that result from under sampling the array. Adaptive algorithms provide the ability to cancel unwanted jamming and can use low gain auxiliaries, subarrays, and high gain beams as spatial degrees of freedom; each of these work best against jamming located in specific regions of the antenna pattern.
