DUAL-MODE ROLL/NOD GIMBALLED SEEKER FOR A FORMING WARHEAD
A dual-mode roll/nod gimballed seeker is configured to provide an unobstructed path for a forming-warhead penetrator. A nod assembly includes first and second seekers separately offset from the roll axis whose FOV overlap within a stand-off range to a target.

This alleviates the need for a precursor charge and saves precious volume in the airframe, which is of particular import for small diameter warheads, in particular those having a diameter of no more than 8 inches.

Vibration compensation is provided for Interferometric Noise Suppressed Oscillators (INSOs). In an INSO the error signal at the mixer output responds linearly to changes in carrier frequency. A vibration compensation signal is summed with the error signal at the input to the feedback amplifier to provide the control signal to the loop phase shifter to suppress close-in phase noise near the carrier frequency and to reduce the effects of mechanical vibrations on oscillator phase noise. The addition of the vibration compensation signal does degrade carrier suppression, hence increases the flicker noise contributed by the INSO's LNA but does so without degrading overall oscillator phase noise. In a frequency tuned configuration, the vibration compensation signal reduces the effects of mechanical vibrations on oscillator phase noise independent of the tuning voltage applied to the phase shifter.

The design of an existing air-to-air missile seeker is adapted to new missions that require both active laser illumination and detection (passive or active) capabilities. The gimbal is used to point the laser beam to a desired location in a transmit FOR. This approach minimizes the size, weight and power of the sensor because only a small portion of the transmit FOR is illuminated at any instant. This minimizes the laser output required, which reduces the power to operate the laser and the power to maintain the laser at operating temperature. In existing seekers, the gimbal points the detector in the desired direction to expand its FOR. To address the limitations of coupling the laser beam into the gimbaled optical system, the gimbal cannot perform the steering function for the detector. Instead, a staring detector receives light through an off-gimbal aperture within a fixed receive FOR that overlaps the transmit FOR.

In a system for covert sensing and communications a broadband light source is encoded using spread spectrum waveform coding to spread a narrow-band signal over frequency. The modulated broadband light is suitably hidden in additional noise and then split into two portions, a first portion of which illuminates a target, and a second portion of which is delayed and provided as a local oscillator. Light reflected from the target is combined with the local oscillator, detected using heterodyne, homodyne or quasi-homodyne techniques, demodulated and decoded to estimate the phase of the reflected light relative to the transmitted light to provide fine range estimates for the target. Waveform coding allows for time-correlation of the transmitted and received coded waveforms to provide improved resolution for adjusting the delay of the local oscillator to improve the detection schemes. The waveform coding also provides a covert communications channel.
