摘要： A sensing device is described that is configured to be launched from an air vehicle for deployment on the ground. The sensing device includes at least one sensor, an inertial measurement unit (IMU), at least one flight control surface, a flight control unit configured to control a position of the flight control surfaces, and a processing unit. The processing unit is coupled to the IMU and is configured to receive a desired trajectory from an external source and, upon launch of the sensing device, is further configured to determine an error between the desired trajectory and a current position as determined by the IMU. The processing unit is also configured to cause the flight control unit to adjust a position of the flight control surfaces to minimize the error.

摘要： In one aspect, a method of radar altimeter operation including a time dependent gain control is described. The method comprises triggering a Sensitivity Time Control (STC) gain control signal at a pulse repetition frequency (PRF) of a transmit pulse to attenuate interference from at least one of an antenna leakage signal and a signal reflected from equipment. The method also includes shaping the STC gain control signal from no attenuation at a first time, before a transmitter sends the transmit pulse, to a stable maximum attenuation at the time the transmitter sends the transmit pulse, to no attenuation at a second time, after the transmitter sends the transmit pulse. The method also includes matching a bandwidth of an intermediate frequency (IF) amplifier to the pulse width of a transmitted pulse.

摘要： A method for controlling a detonation altitude of a radar equipped munition is described. The method includes calculating a velocity of the munition while the munition is at an altitude greater than the desired detonation altitude, determining when the munition is at a reference altitude, and calculating a time representing when the vehicle will reach the desired detonation altitude based on the calculated velocity and determined reference altitude. The method also includes generating a fusing signal to detonate the munition after the calculated time has passed.
