A guidance system for actively guiding a projectile, such as a bullet after it has been fired from a gun. The guidance system includes a radar unit that includes a plurality of receiver arrays. An optical scope is also mounted to the gun for optically sighting a target. An inertial measurement unit provided on the gun locks onto the target after it has been sighted by the scope, and provides a reference location at the center of the receiver arrays from which the bullet can be directed. The receiver arrays receive radar monopulse beacon signals from the bullet. The signals from the bullet are used to identify the position of the bullet and the roll of the bullet. The signals sent to the bullet provide flight correction information that is processed on the bullet, and used to control actuators that move steering devices on the bullet.

A vertically integrated electronically steered phased array that employs beamsteering using a programmable phase locked loop including a local oscillator. The local oscillator provides an oscillator signal that is converted to an RF signal that can be either up-converted for a transmit operation or down-converted for a receive operation. The relative off-set between independently generated local oscillator signals forms the basis of the off-set phase required for a phased array. The absolute measure of off-set phase is referenced to a globally distributed clock signal that aligns the zero degree phase shift of the oscillator.

A radar system is disclosed, which comprises an orthogonal frequency division multiplexing (OFDM) modem and a frequency scanning antenna. In transmit, the OFDM modem modulates radar waveforms and the frequency scanning antenna radiates the OFDM modulated radio frequency (RF) energy. In receive mode, the frequency scanning antenna captures the echoes and the OFDM modem demodulates the echoes. Directionality of the frequency scanning antenna is dependent upon RF carrier frequency. In other features, the radar system further comprises a transmit/receive (T/R) module that up-converts and amplifies the OFDM modulation, and outputs the amplified signal to the frequency scanning antenna. The T/R module amplifies and down-converts a received RF echo from the frequency scanning antenna and outputs the down-converted echo to the OFDM modem. A plurality of scanning angles are measured simultaneously.

The present disclosure provides systems and techniques that can be implemented in a gun, such as an electromechanical gun. The gun may charge a capacitor bank, identify a trigger break based on an output generated by a trigger sensor, and transmit a signal based on the trigger break. Transmitting the signal may result in the capacitor bank discharging electric charge such that electric current is directed at an actuator mechanism so as to cause displacement of the actuator mechanism, and the displacement of the actuator mechanism may result in the propulsion of a projectile through a barrel of the gun. The gun may determine that a projectile has been fired based on an output of an accelerometer or a gyroscope, and the gun may recharge the capacitor bank in response to determining that the projectile has been fired.

The present disclosure provides systems and techniques for an electromechanical sear that is implementable in a gun. The gun may include a fire control manager, and the fire control manager may identify a trigger break based on a trigger sensor, transmit, based on the trigger break, a first signal to a first actuator located in a displacement path of a sear, so as to cause the first actuator to be displaced in a first direction, and transmit, based on the trigger break, a second signal to a second actuator located in the displacement path of the sear, so as to cause the second actuator to be displaced in a second direction. The transmitting the first signal to the first actuator and the transmitting the second signal to the second actuator may cause displacement of the sear and firing of the gun.
