摘要： An automatic thresholding reference and detection circuit which generates a signal in time which is a replica of the radar return signal's doppler spectrum. The radar signal return is processed by a target signal channel having a narrow bandwidth filter which produces a fine resolution replica of the signal spectrum, and by a reference signal channel having a wider bandwidth filter, which produces a smeared (or average) replica of the signal spectrum. The output of the reference signal channel is a threshold signal which, when compared to the output of the target signal channel, allows only the target signals to be passed for further processing and rejects clutter and thermal noise.

摘要： A chopperless ambient field apparatus and method is described having top and bottom sensing plates; a transistor-based device having first, second and third terminals; a first signal line coupled to the top plate and the first terminal of the device; a second signal line coupled to the bottom plate and the second terminal of the device; at least one controllable grounding circuit coupled to at least the first and second plates and to the first terminal of the device; an electrical parameter detector coupled to the second and third terminals of the device; and a protective enclosure disposed about the top and bottom plates, the device, and the detector, wherein with control of the grounding circuit, the detector measures AC fields and quasi-static DC electric fields impinging on the plates. A calibration procedure converts the unit to a DC measuring device.

摘要： An arrangement for recoilless launch including a non-gaseous reaction mass having a weight in a range of about 25% to about 75% of a weight of a projectile. For the same projectile energy, less propellant is required than a rocket, which minimizes backblast and reduces before-launch weight. The recoilless launching is adapted to shoulder-launched projectiles in a confined space. The reaction mass may be particles associated with a propellant so as to be released concurrently as the propellant turns into gas and accelerated by and with the propellant gas in a nozzle.
摘要翻译：一种无后坐力发射装置，包括非气态反应物料，其重量在射弹重量的约25％至约75％的范围内。对于相同的射弹能量，需要比火箭更少的推进剂，这可以最大限度地减少反弹并减少发射前的重量。无后坐力发射适用于在密闭空间内肩扛射弹。反应物料可以是与推进剂相关联的颗粒，以便随着推进剂变成气体并在喷嘴中被推进剂气体加速和加速，同时释放。
