A method for calculating a center frequency and a bandwidth for a radar doppler filter is herein described. The center frequency and bandwidth are calculated to provide radar performance over varying terrain and aircraft altitude, pitch, and roll. The method includes receiving an antenna mounting angle, a slant range, and velocity vectors in body coordinates, calculating a range swath doppler velocity, a track and phase swath bandwidth, and a phase swath doppler velocity. The method continues by calculating a range swath center frequency based on the range swath doppler velocity, calculating a phase swath center frequency based on the phase swath doppler velocity, and calculating a level and verify swath bandwidth based upon the track and phase swath bandwidth.

Methods and apparatus for determination of a filter center frequency

A method of determining a target location from a vehicle is described. The method includes identifying the target utilizing a video system, determining an angular location vector to the target with respect to the vehicle, determining a position of the vehicle utilizing a digital terrain elevation map and precision radar altimeter, calculating a location where the angular location vector would intersect with the digital terrain elevation map, and generating a target position based on vehicle position and the location of the intersection of the angular location vector and digital terrain elevation map.

Systems and methods for target location

An ultrasonic distance measuring system for monitoring railroad car loads. The system includes an ultrasonic transducer, a pulse generation and detection circuit and a measurement circuit. The transducer produces a transmitted ultrasonic pulse beam to be directed at a load in a railroad car and receives a return pulse beam from the load. The pulse generation and detection circuit is coupled to the transducer and causes the transducer to produce the transmitted pulse beam. A return pulse beam is detected by the pulse generation and detection circuit. The measurement circuit is coupled to the pulse generation and detection circuit and generates a measurement signal representative of the load as a function of the time delay between the transmitted and return pulse beams.

Ultrasonic distance measuring system for monitoring railroad car loads

A remotely operated rail car status monitor and control system including a plurality of handbrake status and release monitors (HSRMs), each of which is mounted to an individual rail car of a train, and a handheld data terminal (HDT). The HSRMs are self-contained electronic sensing and control devices capable of short range radio frequency (RF) communication with the HDT, and are mounted to rail car handbrakes configured for remote release. Each HSRM is programmed with a unique ID code which corresponds to the rail car's identifier. The HSRMs monitor and record the operational state of systems on the rail car such as the handbrake, load weight and refrigerator car temperature. Operating characteristics of the train such slid wheel events and handling impacts can be monitored and stored. Systems of the rail car such as the handbrake can also be released or otherwise controlled. The HDT is a self-contained portable electronic device by which an operator can effectively and conveniently communicate with individual HSRMs by using their unique ID codes. Using the HDT an operator can retrieve information on the current operational state of the rail car handbrake and other systems, and information on the train operating characteristics. The handbrake and other systems can also be remotely released or otherwise actuated through use of the HDT. Information retrieved by the HDT can be stored and displayed on the device or downloaded to a computer.
