SYSTEM AND METHOD FOR EFFICIENT DIRECTIONAL DISCOVERY OF COMMUNICATIONS TERMINALS VIA BEAM INTERLEAVING
A node of a multi-node network includes a communications interface incorporating one or more paired antenna elements wherein a transmitter (Tx) element and receiver (Rx) element are oriented in opposing directions. The node discovers and/or links to other nodes of the network by orienting each paired antenna element to transmit to other nodes in one direction and receive in the opposing direction (e.g., through a transmit and receive region, the transmit region opposite the receive region). At subsequent time intervals (e.g., alternating with the first time interval or set thereof), the Tx antenna elements transmit in directions through the initial receive region, each transmit direction interleaved between two prior receive directions, while the Rx antenna elements simultaneously attempt to receive in opposing directions through the initial transmit region, each receive direction interleaved between two prior transmit directions.

The mixer-first topology of receivers do not include low-noise amplifiers (LNA) preceding the mixer. The Mixer-First topology of radio receivers utilizes a direct-conversion quadrature mixer to down convert an RF signal to baseband, where a Hilbert Transform filter is used for sideband selection. When a switching mixer is used, the mixer-first receiver is capable of extremely high dynamic range and linearity. The downfall of the mixer-first topology is poor out-of-band signal rejection. A mixer-first receiver is described which achieves third-harmonic rejection without bandpass filtering proceeding the mixer.

A communication system applies impedance matching to an antenna specific to individual samples of a transmit signal. The system samples a signal and identifies the peak frequency content of each sample. Based on the peak frequency content, the system identifies an impedance match for a given antenna that provides the greatest energy transmission. The sampled portion of the signal is delayed to accommodate processing time to determine the impedance match and control settings. Control settings may be applied via discrete digital circuitry or continuous analog circuitry.

AESA-BASED SYNTHETIC NULLING FOR ENHANCED RADAR GROUND CLUTTER SUPPRESSION
A radar system uses multiple nulls to improve detection capabilities. Multiple radar pulses are transmitted and or received, each with a different null pattern. The returns from each pulse are averaged together to form a null window that is less noisy and potentially wider than a single null pattern. This approach can improve the signal-to-noise ratio and make it easier to detect objects of interest. The system may generate individual pulses from an AESA divided into several subarrays. Each subarray produces a pulse with a null in a different location in the radiation pattern centered about a location of interest. The contemporaneous return signals are averaged together.
