A dual-mode seeker for a guided missile, the dual-mode seeker comprising: a semi-active-mode target locator configured to: detect laser pulses reflected by a target within a scene aligned along a missile axis, each of the laser pulses projected onto the target by a remote Laser Target Designator, LTD, thereby designating the target; determine, based on the detected laser pulses, a direction of the designated target relative to the optical axis; and generate an output signal indicative of the direction of the designated target relative to the missile axis; a passive-mode target locator configured to: capture Short-Wavelength InfraRed, SWIR, images of the aligned scene, each of the SWIR images captured at an exposure time period in which the remote LTD is not projecting a laser pulse onto the designated target; identify an image feature within each of the SWIR images, the image feature corresponding to the designated target; determine, based on the identified image feature, the direction of the designated target relative to the missile axis; and generate an output signal indicative of the direction of the designated target relative to the missile axis, the seeker being characterized by: an active SWIR illuminator aligned parallel to the missile axis and configured to: illuminate the aligned scene during an illumination time offset by a predetermined Phase Offset Interval, POI, from a time period in which the laser pulses are projected by the remote LTD. a semi-active-mode target locator configured to: detect laser pulses reflected by a target within a scene aligned along a missile axis, each of the laser pulses projected onto the target by a remote Laser Target Designator, LTD, thereby designating the target; determine, based on the detected laser pulses, a direction of the designated target relative to the optical axis; and generate an output signal indicative of the direction of the designated target relative to the missile axis; detect laser pulses reflected by a target within a scene aligned along a missile axis, each of the laser pulses projected onto the target by a remote Laser Target Designator, LTD, thereby designating the target; determine, based on the detected laser pulses, a direction of the designated target relative to the optical axis; and generate an output signal indicative of the direction of the designated target relative to the missile axis; a passive-mode target locator configured to: capture Short-Wavelength InfraRed, SWIR, images of the aligned scene, each of the SWIR images captured at an exposure time period in which the remote LTD is not projecting a laser pulse onto the designated target; identify an image feature within each of the SWIR images, the image feature corresponding to the designated target; determine, based on the identified image feature, the direction of the designated target relative to the missile axis; and generate an output signal indicative of the direction of the designated target relative to the missile axis, the seeker being characterized by: an active SWIR illuminator aligned parallel to the missile axis and configured to: illuminate the aligned scene during an illumination time offset by a predetermined Phase Offset Interval, POI, from a time period in which the laser pulses are projected by the remote LTD. capture Short-Wavelength InfraRed, SWIR, images of the aligned scene, each of the SWIR images captured at an exposure time period in which the remote LTD is not projecting a laser pulse onto the designated target; identify an image feature within each of the SWIR images, the image feature corresponding to the designated target; determine, based on the identified image feature, the direction of the designated target relative to the missile axis; and generate an output signal indicative of the direction of the designated target relative to the missile axis, the seeker being characterized by: an active SWIR illuminator aligned parallel to the missile axis and configured to: illuminate the aligned scene during an illumination time offset by a predetermined Phase Offset Interval, POI, from a time period in which the laser pulses are projected by the remote LTD.
